This is a pentagonal hexacontahedron, the dual of the snub dodecahedron. It’s decorated with mandalas of the the type I blogged here, two posts ago. The mandalas do interesting things when this polyhedron is stellated, as you can see below.

That was the first stellation, and here is the second:

The sixth stellation was the last one I found interesting enough to post.
