It's basically a Rubic's cube done with a dodecahedron. The computer model was done so I could visualize the pieces out properly. I tried to construct a physical model based on the simulation plus various disassembled cubes, but I couldn't figure out a way to keep the whole thing together.
It's fully functional, but rather user unfriendly to play. Basically it's all keyboard commands except that the light can be moved using the mouse.
Maybe later I'll add it to the GDS. Who knows.
