This displays 2D projections of the sequence of 3D objects which are the projections of the 4D analog to the cube: as a square is composed of four lines, each touching two others; and a cube is composed of six squares, each touching four others; a hypercube is composed of eight cubes, each touching six others. To make it easier to visualize the rotation, it uses a different color for the edges of each face. Don't think about it too long, or your brain will melt. See also "polytopes" for a more general version of this using OpenGL. http://en.wikipedia.org/wiki/Hypercube http://en.wikipedia.org/wiki/Regular_polytope Written by Joe Keane, Fritz Mueller, and Jamie Zawinski; 1992.
