Well each of them is a combination of five shapes rotated around the center of
a face of a dodecahedron. There were other interesting rotations in that
book, couldn't remember them when I got home though. I will have to go back
to that library soon. Source is below, get macros2.inc from David Fontaine's
page, and polyhedra,inc from my page.
