My first encounter with four-dimensional polytopes was Jenn 3D (2001-2007) by Fritz Obermeyer. Jenn describes itself as follows:
Jenn is a toy for playing with various quotients of Cayley graphs of finite Coxeter groups on four generators. Jenn builds the graphs using the Todd-Coxeter algorithm, embeds them into the 3-sphere, and stereographically projects them onto Euclidean 3-space.
Wow. This description made absolutely no sense to me when I first read it - none of these terms were familiar to me. My purpose with this page is to go through this description step-by-step and explain the various terms.
We will also go one step further, and discuss how these structures can be ray traced in realtime. This can be done using a clever (inverse) construction technique of folding space into a fundamental domain. The technique was originally described by Abdelaziz Nait Merzouk (aka Knighty) in a Fractal Forums thread from 2012.
Symmetries of the cube
We will start out in three dimensions with a familiar object: the cube.
The cube has several automorphisms - transformations that will map the cube onto itself. For instance, we can easily find several rotations (between opposite vertices: 4 (120 degrees), opposite mid-edges: 6 (180 degrees), and opposite faces: 3 (90 degrees): a total of 4*2+6*1+3*3 = 23 rotations.
Including the identity transformation, and taking into account that we could also mirror each one of these transformations, we arrive at 48 automorphisms for the cube.
Besides the rotation symmetries above, we can also depict the reflection symmetries. Shown to the right are the 9 different such reflection operations, that will map the cube onto itself (although in a mirrored version).
These 48 transformations form a group: a set of elements, together with a rule for combining any two elements such that the result is again an element in the set. There must an identity element in the group, and every element must have an inverse element: i.e. an element such that combining the element and its inverse results in the identity element.
In our case, combining any number of the 48 transformations will result in a transformation that is already present in our set of transformations. Likewise, for all rotations and reflections, there exists an inverse transformation (for 180 degrees rotations, and for reflections, the transformations are their own inverses).
These transformations are not independent: some transformations can be expressed by combining other transformations. Perhaps it is possible to find a smaller subset of transformation that could be combined to form all the 48 automorphisms?
This is known as a set of generators: a subset, S, of elements in the group G, which can be used to express all elements.
For the cube, it is possible to find a set of three reflections, which can be used to form all the 48 transformations. One such set is shown to the right: here we have three reflection planes, which we could think of as operators - let us call them R, G, and B after their colors. This set can be used to construct all other transformations.
Notice that the angle between the reflection planes (sometimes called mirrors) is: $$\angle(R,G) = 45^{\circ} $$ $$\angle(G,B) = 60^{\circ} $$ $$\angle(R,B) = 90^{\circ} $$
Now, combining two reflections results in a rotation of twice the angle between the reflection planes. So applying e.g. GB would be equal to a rotation of 120 degrees. And applying GB three times, e.g. GBGBGB, would not change the input.
This means we can establish the following relations between the generators:
$$R^2 = B^2 = G^2 = (RG)^4 = (GB)^3 = (RB)^2 = I$$Given a set of generators, how many different elements are there in our set? And can we decide whether two compositions (say RGRG and RBG) are identical operations? This turns out to be a computationally hard problem, known as the word problem for groups. But for some specific groups, this problem is computationally tractable.
The Todd-Coxeter Algorithm
Our example relations above form a special group, called a Coxeter group. That is a group where the generators have relations of the form: \((ab)^{m_{ab}}\), as above: $$(RG)^4 = (GB)^3 = (RB)^2$$ The generators must also be their own inverse: $$R^2 = B^2 = G^2$$ Since the generators are their own inverses, they can be associated with reflections.
For Coxeter groups, it is possible to identify all elements in the group, given the generators. The Todd-Coxeter Algorithm provides a way to identify and count all elements generated by our generators. (Quick digression: The Todd-Coxeter algorithm was one of the first non-numerical algorithm to be implemented on a digital computer - using an EDSAC 1 in 1953)
Actually, the Todd-Coxeter algorithm does a bit more than counting the elements: it also allows for enumerating all cosets of G, for a given subgroup H.
What does this mean?
A coset is the set resulting from multiplying all members in \(H\) by a group element \(g\) from \(G\). A (left) coset is written \(gH\). The number of cosets is written \(|G:H|\). Lagrange's theorem states that \( [G:H]={|G| \over |H|} \). All the cosets for a given subgroup form a new set, called a quotient set (denoted G/H).
The algorithm works by keeping track of several tables: a coset table (listing the generator actions on the different cosets), a subgroup table (listing subgroup generator actions), and a table for each relation between the group generators. The algorithm works by filling out rows in these tables. Once a row is closed, a (potentially) new piece of information is known.
Here is a demo (use the 'step' button to fill the table):
Group: Subgroup: Step
Let us look at the various cosets you get when you use Todd-Coxeter on the symmetry groups for the regular polytopes, using different subsets of the generators to specify a subgroup:

| Vertices | Edges | Faces | Cells |
An interesting structure emerges here: looking at the cosets for the subgroups generated by leaving out one of the generators, the number of cosets matches the number of vertices, edges, or faces! It seems we can fully describe the geometric structure by forming various quotient sets.
Also notice, that the ordering matter here: the cube and octahedron have the same generators (just switch 'r' and 'b'), and same symmetry group, but the number of faces and vertices are swapped. These shapes are said to be dual. The Dodecahedron/Icosahedron, the 8-cell/16-cell, and 120-cell/600-cell all form dual pairs.
So what differentiates a cube from an octahedron? The answer is, that it depends on how the initial vertex is placed. Notice the outer circle on the first reflector, r, in the Coxeter diagram: this circle specifies that the initial vertex should be placed somewhere off the reflection plane for r, but on the reflection planes for g and b. (This also means that the initial vertex would be taken to itself when applying g and b).
Let us explore the quotient sets a bit more: how do we generate the geometry and how do we associate edges with vertices?
Generating geometry from group structure
We will recreate the Euclidean geometry from the abstract Coxeter group description.
Given the generator relations, we know the angles between the reflector planes: If there is a relation on the form: \((RB)^{N}\), the angle between the reflection planes R and B must be \( \pi / N \) - which again corresponds to a rotation of \( 2\pi / N \) degrees. For the cube the angles between the reflection planes are 45, 60, and 90. The first step is to create a set of reflection plane normal vectors with these angles between them. This can be done iteratively, by starting with an arbitrary unit vector, and adding vectors at corresponding angles, e.g.:
$$ \begin{pmatrix} & 1 \\ & 0 \\ & 0 \end{pmatrix}, \begin{pmatrix} & cos(\theta_{12}) \\ & N_1 \\ & 0 \end{pmatrix}, \begin{pmatrix} & cos(\theta_{13}) \\ & \frac{cos(\theta_{23})-cos(\theta_{12})cos(\theta_{13}) }{N_1} \\ & N_2 \end{pmatrix} $$
These vectors are the normals of the reflecting planes (The N's are normalization constants that can be trivially calculated - all the normals must be unit length).
We now have our reflection planes (the group generators) defined. Given a starting point, we can apply these and create the full geometry. But how do we choose the starting point? As previously mentioned the cube and octahedron share the same generator relations (they are dual). So why are they different? Looking at their coxeter diagram in the table above, this has to do with the special outer circle. This outer circle has a special meaning: the initial starting point should be located on the two other reflection planes (the blue and the green), but not on the red one.
We can use Gram-Schmidt orthonormalization to create a vector that is contained in the blue and the green plane, but not in the red plane. We do this by starting out with the three reflection plane normal vectors in the order blue, green, and red. After applying Gram-Schmidt to this set of vectors, the last vector in the transformed set will be orthogonal to the blue and green reflection plane normal vectors (and thus be located on the intersection of these two planes). The advantage of using Gram-Schmidt is that we can generalize this to four dimensions - if we had used the cross product, that would not have been possible.
The example below shows how this works for the dodecahedron. Like the cube, the dedocahedron can be generated by three generators, with angles 36, 60, and 90 degrees between the reflecting planes.
The table can be used to explore how the different quotient sets ties the vertices, edges, and faces together. Try hovering an entry.
For instance, see how vertex V0 connects to three edges (E0,E1,E3) and three faces (F0,F1,F2). Likewise, edge E0 connects two vertices (V0,V1) and two faces (F0, F1). The face F0 connects five vertices (V0,V1,V2,V3,V5) and five edges (E0,E1,E2,E4,E6)
Also notice the volume enclosed by the three arrows. This is the fundamental domain, which will we return to in the next section.
Ray tracing reflection groups
I have long been a fan of ray marching, and distance estimation techniques.
The previous section showed how to construct geometry by explicitly calculating positions for vertices, edges, and faces, and then displaying the structures by rasterizing polygons (using WebGL).
But it is possible to construct very efficient distance estimators for the reflection group polytopes - including the four-dimensional ones. Utilizing modern GPUs, this makes it possible to ray trace high-quality images in real-time.
This technique was originally described by Knighty in this Fractal Forums thread from 2012.
The basic idea is a clever trick: instead of trying to calculate the positions of all vertices and edges, we will first transform (using the group reflections) all points in space into the same 'fundamental' region or domain. The basic building block will be a fold: a simple conditional reflection - if we are on the wrong side of a reflection plane, we will do the reflection - otherwise not. Once our paths of folds ends in the fundamental domain, we can quickly test whether we are inside a vertex, edge, or plane (at least after assigning a width to these objects). We can also calculate the distance to the nearest part of the structure this way.
Being able to calculate the distance to the nearest part of a structure is very powerful. Given this distance estimator, we can render our object using ray marching: we can take steps along a ray from the camera, and stop once we are sufficiently close to the object. The distance estimator tells us how large steps we are allowed to march. And, since we now know how to determine how an arbitrary ray intersects our structure, we can ray trace it, including shadows and reflections. I previously described the technique here for a recursive tetrahedron.
The illustration above shows how to fold a point in space (the red ball) back into the fundamental domain (move to this region). You can move the red ball using the controls. By repeatedly applying the folds, we can trace a piecewise linear path back to the fundamental domain (the white ball shows the end point in the fundamental domain). Once in the fundamental domain, we can calculate the distance to the initial vertex: this distance is shown by the thin white line. Due to the symmetries, this is the same as the distance to the closest vertex of the red ball! The distance is visualized as the radius of the red sphere centered on the red ball.
How many folds do we need? It seems like the worst case is when the point is located in "mirrored" fundamental domain (move to this region). In this domain, 15 folds (3 generators x the max symmetry of 5) are required.
It may not seem the advantage is that big: we could have explicitly calculated the 20 vertices and 30 edges and calculated the distances to those. But for more complex structures (the 120-cell has 600 vertices and 1200 edges), the advantage is huge: the number of regions that can be folded back into a fundamental domain grows exponentially with the number of fold operations. And fold operations are cheap: for instance, in the example above, two of the reflections are orthogonal and can be aligned with the coordinate system axes. In that case, the fold operation may be implemented simply by taking the absolute value of the coordinates, e.g. pos.xy = abs(pos.xy). A very fast operation!
The folding approach also has another advantage: we do not require the elaborate coset structure of the symmetry group to figure out how the vertices are organized into edges and faces. We only need to describe the fundamental domain, then symmetry will take care of the rest.
Now we are ready for a real example of ray tracing a system of three generators:
In the example above, the U, V, and W parameters control the position of the initial vertex as specified in a coordinate system where each axis lives on the intersection of two reflection planes (the same coordinate system as defined in the dodecahedron example with the red, green, and blue arrows).
When the 'displayFundamental' option is enabled, the initial vertex will be displayed by a black line. The U,V, and W vectors are shown as white lines, and define the fundamental region (and any pair of white lines span a reflection plane).
When only U is enabled (i.e. non-zero), we get a regular polyhedron. But when we enable some of the other mirrors, we will get various uniform polyhedra. For instance, only enabling W will give us the dual of the original regular polyhedron. Enabling U and V will give us a truncated polyhedron.
The Degree parameter controls one of the angles between the reflection planes (e.g. 3 = 60 degrees, 4 = 45 degrees, 5 = 36 degrees). The two other angles are always 90 degrees and 60 degrees.
Notice, that the resulting structures are all convex, but not necessarily regular polytopes.
The fourth dimension
To get to the fourth dimension, we need one additional trick: the stereographic projection.
Stereographic projection is a projection from the surface of a sphere (in 3D) to a plane in 2D. In the example above, we have our cube embedded in a sphere in 3D. Notice, that the vertices will all be on the sphere surface - this is true for all regular polyhedra, also in four dimensions.
The edges of the cube are black. These are projected (the red lines) by following a point on the top of sphere, through the vertex, and down on the plane. The projection edges are drawn in green.
It is possible to rotate the cube using the controls. Notice, how the edges are curved when projected down onto the plane, even though they are straight in the cube. That is a choice: this corresponds to 'inflating' the cube onto the sphere, making the edges live on the great circle arcs.
The stereographic projection can be generalized to higher dimensions. This is how we will create our depictions of four dimensional polytopes. We will start out with a 3-sphere in four-dimensional space. The vertices of the polytopes will be placed on the surface of the 3-sphere, and we will make a projection onto 3-dimensional space.
Putting it all together
Here is the final example - ray tracing a system of four generators:
Similar to the 3D example, the U, V, W, and T parameters control the position of the initial vertex and the Degree parameter controls one of the angles between the reflection planes.
There is a set of controls for rotating the 4D object - this is similar to rotating the cube before projecting it down onto the plane in the previous illustration. Notice, that the rotation is not a true 4D rotation - only three coordinates get rotated. For some rotational values, the image gets fuzzy - I think this is when a vertex is close to the projection point of the 3-sphere and gets blown up.
The presets can be used to quickly toggle between the regular 4D polychora.
There is one technicality that has to be taken into account when ray marching 4D polytopes. We march the ray in three dimensions - so in order to get the distance estimates we do an inverse stereographic projection to get to a four dimensional point (see also Knighty's original description).
Once in 4D, we can calculate the distance estimate by folding the point back into the fundamental domain.
In Summary
Many different geometric objects can be described by their Coxeter diagram, e.g. . This diagram describes the structure of the symmetry group by defining relations between the generators. The generators can be interpreted as reflections - and the power of the pair-wise relations describes the angle between the reflection planes.
The Todd-Coxeter algorithm makes it possible to construct all elements in the symmetry group only from the description of the generator relations. It also allows us to find all cosets for a given sub-group. As we saw, by looking at the cosets for generator subgroups, we can identify edges, faces, and cells.
Based on this we can construct an explicit geometry by choosing a starting point and applying the group transformations. For the regular polytopes, the initial vertex must be placed on the intersection of all reflection planes, except one.
Instead of explicitly constructing all vertices, edges, and faces, it is possible to use a different approach: we can construct a function that for each point in space determines how close we are to a vertex or an edge - a distance estimator. We can do this by folding a given point in space repeatedly, until we reach our fundamental domain. This is powerful, because there are efficient methods for ray marching distance estimators (and it parallellizes trivally on GPU's).
All of the above will work in any number of dimensions. However, in order to do the actual visualization, we used (inverse) stereographical projection to reduce the number of dimensions from four to three.
Group theory and symmetries have been studied extensively by the math community, but most of the results are not very accessible unless you are a trained mathematician.
This page is barely scratching the surface. I hope to get some time to look into hyperbolic geometries and honeycombs, both of which would fit naturally together with the regular polytopes - but until then take a look at some of the links below.
A secondary goal with this project was to build a more engaging and interactive web presentation than the static blog entries I usually write - I have been very impressed with what has been happening on sites like Bret Victor's Worry Dream and Distill.pub. My most important lesson learned here, is that building interactive presentations do take up a lot of time (duh). Some of this was partly because I needed to learn new techniques and create a couple of tools from scratch (like building a small three.js framework for ray tracing - including automatic generation of an UI for setting the uniforms). I plan to carve out some of these tools to make them easier to reuse for future projects.
All of the full width images were created using Fragmentarium, which comes with several of Knighty's scripts. The source for this page can be found on Github.

It was closer than might have been expected, but all that matters is that it's yet another win and another step closer to promotion. A first half goal from the excellent Andy Spencer has taken us 15 points clear of 3rd place Weston - although they have 2 games in hand - and 6 points clear of Chippenham in second place.
There's been discussions about setting up an Official Supporters Club recently. Read Kev Crook's letter for more information on a subject which has already led to some interesting debates.
The strange way the fixture list works out this year means we host Moor Green in the Worcester Senior Cup semi-final on Saturday in an interesting distraction from important matters.

Kristin Claire Courington
Unafffiliated
While mainly a homemaker and stay at home mom I also do part-time business consulting work for the Evergreen Children's Chorale.
I have earned a Bachelor of Science in Business Administration degree from Duquesne University in Pittsburgh, PA (2007) and a Master of Public Administration degree from the University of Colorado Denver (2010).
80439-5825
Although I have been registered as an unaffiliated voter I contributed to the Clinton/Kaine campaign in 2016 and the Biden/Harris campaign in 2020. I volunteered with the organization Vote Forward in letter writing campaigns to register new voters in 2020.
I am a volunteer for the hiking group "Hike it Baby" at the local and national level, have been a member of the Wilmot Elementary PTA for two years and a Girl Scout troop leader since July 2019. Through work with the Evergreen Children's Chorale I am involved in various committees and other coalitions for local performing arts and nonprofit groups. I am a member of the Evergreen Sustainability Alliance.
While working as the VP of Program Services for Girl Scouts in the state of Colorado I was responsible for traveling statewide to support members, volunteers, and staff across all regions. I was the Director for the Girl Scouts of Colorado Hispanic Initiative and led other interest groups and initiatives as well (such as our STEM, healthy living, and environmental programming). These projects required working with a variety of business and individual stakeholders from rural, suburban, and urban areas and from many diverse backgrounds. The organization went through a variety of mergers and restructuring across all levels during my 7 years of employment and I was very involved in the development and implementation of these changes. With the Evergreen Children's Chorale I have a role in building partnerships with other area organizations to advocate for the performing arts community across the region.
I believe the members of the commission should represent a diverse group of Colorado citizens and voices like mine often do not have a seat at the table. I enjoyed the restructuring work I was involved with at the Girl Scouts of Colorado and the coalition building I've done with the Evergreen Children's Chorale and feel that my experience would contribute to the Colorado redistricting commission. Having been born in Colorado and raising two children here I feel very passionate about doing my part to ensure our state has a thriving democracy.
Through programming work at the Girl Scouts of Colorado and as a local troop volunteer, the characteristics of teamwork, honesty and fairness as well as civic engagement are qualities I've been working to help instill in young people for over 15 years. I believe I role model these characteristics through my everyday actions across my professional and personal life and will be able to bring these deeply held values to the commission. Conflict resolution and partnership building are two main focus areas of the consulting work I have done for nonprofit organizations over the past 10 years.
Beginning with my capstone project in 2010 at the University of Colorado Denver, I have been involved with nonprofit fund development. Fundraising work requires analyzing donor databases as well as other funding sources, developing detailed plans and budgets, and a knowledge for how to effectively complete the work of strengthening an organization's mission. Through the process or researching, writing and reporting on both private foundation and government grants I have proven success in increasing funds for organizations by utilizing analytical skills as well as logic and reason.

"The Cider House Rules" (1999)
Directed by Lasse Hallstrom Written by John Irving
Starring Tobey Maguire, Michael Caine, Charlize Theron, Delroy Lindo, Paul Rudd, Kathy Baker, Jane Alexander, Erykah Badu, Kate Nelligan, Heavy D, Kieran Culkin, K. Todd Freeman, and J.K. Simmons.
Towards the end of The Cider House Rules, a dying character informs protagonist Homer (Tobey Maguire) of the most important lesson in life: "Sometimes you gotta break the rules to put it straight." The quote sums up the moral of the entire film. Individuals are so unique that they must create their own rules to survive and never become enslaved by what someone else thinks is suitable. Tagging along and depending on another person for an enjoyable existence can only make you blind to the rest of the world, you can only see through their eyes, you see what they want to see and don't want to see. Homer at first is blind to the rest of the world. Working in an orphanage performing illegal abortions with his kind mentor Dr Larch (Michael Caine), the bright ingenuous Homer has never seen a city or the ocean or anything at all outside of the small town in Maine where he was born and raised. Even though Homer knows his life contains nothing but joy in which younger orphans lionize him and nurses respect him, he inexplicably yearns for more in life. From the books he has read or from the only film he has ever seen (King Kong), he knows there is much more out there to explore and cherish. When a young couple seeking an abortion visit the orphanage, Homer decides that leaving town with them is the best chance he'll have to answer his curiosity.
The message of the story is very clear, that this boy wants to discover what the world is like by himself, without having to lean on another for assistance. However, throughout the movie, in my opinion, Homer never actually completes his true goal. There are very few times in which he is actually by himself discovering and learning something different from before. It seemed like he left the orphanage to avoid Dr. Larch's protectiveness, yet when he is on his trip, he is always around someone else, as if this other person is a valid replacement for the doctor. Homer hangs around co-workers during work time and at night, around the beautiful and confused Candy (the ubiquitous Charlize Theron) at other times, and around Candy's WWII pilot boyfriend Wally (Paul Rudd) when he is in town. Wasn't the whole point of Homer's travels to discover who he actually his as an individual? Or to make some decisions without asking another person's opinion first? There were a some moments in which Homer takes control but certainly not enough. Another irritating section of the story is that Homer does not even leave the state of Maine in his journey for self-clarification. It doesn't seem like much of an effort if you barely travel a day's worth of time. Supposedly an attempt to "see what the world is really like," Homer doesn't even change time zones. With such a short distance of travelling, it is really hard to believe that Homer has really changed.
These unsatisfactory elements of the plot fortunately have no harm on the fantastic acting from the splendid cast. Delroy Lindo and Michael Caine were particularly superb as completely different men teaching Homer completely different lessons. Tobey Maguire, who understandably is starting to get the same roles in his films, is also perfectly naïve as the main character. The only problem with the acting was that there were so many characters that some talented actors, including Jane Alexander and Kate Nelligan, were underused.
John Irving, adapting his own novel of the same name, writes a fine script, which contains a number of examples of characters breaking the traditional rules to become happier in life.  Lasse Hallstrom (My Life As a Dog, What's Eating Gilbert Grape) adds his talented directorial skills to the picture. The New England scenery is beautifully detailed and colorfully attractive to the eye.
Some unbelievably realistic acting, directing, and screenwriting make The Cider House Rules fun to watch, but afterwards when trying to identify the true moral of the story, some of the details are downright disappointing.

Ernesto Martinez-Garnica, 42, from Milwaukee, was cited for drunken driving after a witness saw him "driving really reckless" and his car "swerving all over the road" on Howell Avenue -- with what they originally believed to be a hawk on his shoulder, according to the police report.
“There’s a guy behind us. … He’s driving really reckless, but he has a hawk in his car,” a 911 caller said, according to Fox 8 WGHP.
FLORIDA WOMAN ARRESTED IN NANNY'S 1999 'BARBARIC' BEATING DEATH, WISCONSIN SHERIFF SAYS
When police caught up with the vehicle they noticed a bird flapping inside. After a closer look, they saw it was a brown chicken, not a hawk, that the suspect decided to bring along for the ride.
Police searched the vehicle and found numerous beer cans and noticed "a live chicken that was fluttering around the inside of the vehicle," the outlet reported.
Martinez-Garnica was given a field sobriety test, which he failed -- netting him his third DWI arrest.

Dashcam footage shows an officer administering the sobriety test on the suspect, while another officer removed the fluttering bird from the vehicle.
The chicken, named "Teresa," was placed in the back of the police vehicle with the driver's cousin -- who had also been riding in Martinez-Garnica's car.
Police say Teresa is safe. She was given to the Milwaukee Area Domestic Animal Control Commission, where she's being kept until the owner claims it, according to Fox 8.

Today (Monday) you should receive a packet of preread materials for the offsite September 20-21. Because a large part of this conference will involve working sessions to discuss objectives and priorities for Global Accounting, we have gathered this material to stimulate ideas and discussion.
On Thursday, you will discuss in breakout groups what you think Global Accounting's top few priorities should be. You should be prepared to consider the following questions, with the ultimate goal of determining and presenting your group's opinion of what the top priorities should be:
Who are (or should be) our customers?
What are their business requirements?
What do they value?
How and how well are we providing value to our customers and to Enron?
What activities should we continue, start, or stop?
If you don't receive your packet of preread materials by the end of the day Monday, please contact me at x36641.

In the past months I have kept being dissatisfied with the recent updates to the linux desktops.
Unity drove me crazy. Xfce felt right, but was still not quite mature, with a few annoying bugs. KDE, my historical favorite - too complex. Gnome 3 - I haven't tried in person. Enough to see my other half struggling to open up the correct terminal (one of three) to issue a make command. Ubuntu with classic gnome -- a thing I could practically live with forever -- exhausting my CPU.
And CPU exhaustion is, apparently, a big deal. Ubuntu with classic gnome is not the only one. KDE, yes, even with effects turned off (I don't want effects, I want to do software development), even with "High resolution and low CPU" setup (Ugh! Low CPU does not mean I don't want font antialiasing!), Gnome 3, Unity with Compiz... I mean, they all want to be so smart. Too smart.
I can hardly find my arms and legs in trying to configure my KDE desktop. So many options! And CCSM... Xfce getting the medal for being the sanest desktop around.
Unity 2D
I accidentally entered with a Unity 2D session. Here's the short summary of differences: it basically looks like Unity, but does not use Comiz. Alt-TAB is very basic (the way I like it) and does not group similar windows etc. You cannot resize icons on dash.
Oh. It does not kill my CPU.
And you can add the tint2 panel. I mean, you can add tint2 to Unity as well, but then it overlaps with the dash, unless you manually configure it to position itself just right after, in which case it looks funny if the dash is hidden, and, ... you get my point.
Unity 2D's dash respects tint2 by making itself shorter. Since I don't actually like nor need the dash for most of the time, I set it to auto-hide. Which leaves me with the top Unity panel, which becomes acceptable one the ClassicMenu indicator is added, and the bottom tint2 panel, showing my windows.
Tint2 respects the workspaces set up by Unity, which is good news. It doesn't work well with context menu (right click on task entry). But it gets the job done, and fairly seamlessly.

Manhunt launched for Brit, 25, missing in Australia bushland after bumping head
Aslan King has not been seen since suffering a medical episode, in which he hit his head before fleeing into nearby bushland, near the iconic Twelve Apostles in Victoria
by Ben WeichA desperate search is underway for a 25-year-old British man who has gone missing in bushland in Australia.
Aslan King was camping with friends near the Twelve Apostles limestone stacks in rural Victoria, before suffering a medical episode.
At about 2am this morning, he hit his head and ran into bushland, the Age reports .
Friends he was camping with launched a search for Mr King but were unable to find him, as officers warned that he may be disorientated and lost in the bush.
Just hours before his disappearance Mr King, an illustrator from Bristol, posted a video of Friday's sunset to Instagram
He also posted clips of his road trip along the Great Ocean Road.
Mr King "suddenly got up and ran from the area into surrounding bushland" in the early hours of Saturday morning, a police spokeswoman said.
The police spokeswoman added: "It’s believed Aslan may be disoriented and become lost in the bush."
Mr King's friends, who are also British, told Australia's Nine News that they had been drinking before he appeared to suffer a seizure.
When his friends tried to restrain him, he started running into bushland.
According to local media, Mr King had only been in the country for weeks before his disappearance.
He was described as a white man of medium build, with short dark hair.
He was wearing tracksuit bottoms, a light grey T-shirt, grey hoodie and green Reebok runners when he went missing.
Police say Mr King may possibly have blood on his forehead.
