Update: I turned this into a full page:  Top 8 Interesting Things to Know about the Rhombic Triacontahedron

Ball of Whacks is a geometry toy. (Available online and in toy stores that sell cool stuff.)whacks

It is a rhombic triacontahedron.  Each of the 30 rhombic faces are golden, in that the ratio of the diagonals is the Golden Ratio.

Good stuff at https://en.wikipedia.org/wiki/Rhombic_triacontahedron

It is the dual of the Icosidodecahedron (which is Archimedean), which is the Hoberman Sphere.

I have a light in my office (which was a gift from my kids) which is the rhombic triacontahedron.
