General Interest:Fractals

The recipe for filling a large dodecahedron with small dodecas involves examing the three stellations of the dodecahedron. Here, the first stellation of the dodecahedron is filled with tiny dodecas. This symmetry is closely related to that of the three-dimensional Penrose tiles, and generalizes to dimension 4 (but no higher).

How to make it: Mathematica wrote the production rules, a program by Dan Krech iterated the rules, GeomView set up the pictures and RenderMan rendered the final result.
