An Icosahedron, Augmented with Twenty Great Icosahedra

The picture above uses symmetry to divide the faces of this polyhedral cluster into color groups. This next one puts faces in the same color-group if and only if they are parallel.

Stellating this once yielded this result, again colored by face-type, like the first image here:

I made these using Stella 4d, which you can try at www.software3d.com/Stella.php.
