Any comments on how it's done? WFL
I'd guess it's something like the dodecahedra in pyrite crystals: http://math.ucr.edu/home/baez/dodecahedron/14.html
That dodecahedron is described as non-regular on its web page. But (as is well-known) a perfectly regular dodecahedron can be inscribed in a perfect cube with 3 pairs of opposite edge passing through the face centers of the 3 pairs of opposite faces, resp., of the cube. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
