These .gifs were made using Stella 4d: Polyhedron Navigator, software you can try for free right here.
In this first image of the final stellation of the icosahedron, the faces are colored with a different color for each face, except for parallel faces, which are the same color.
The next image uses red and yellow to color the facelets by type.
Finally, the third image simply uses rainbow color mode.
I used Stella 4d to make these. You can try this program for free at this website.
This is the compound of two tetrahedra, also known as Johannes Kepler’s Stella Octangula.
I found the five variations of this polyhedral compound shown below, located deep within the stellation-series of the great rhombicuboctahedron.

Here’s the pentagonal icositetrahedron. It is the dual of the snub cube.
And here is its third stellation. As you can see, it’s a compound of two irregular dodecahedra.

A great dodecahedron (red) sits in the middle of this polyhedral cluster. The polyhedra touching the one in the center are blue small stellated dodecahedra. Finally, there are yellow great stellated dodecahedra on the outside.

This compound has three parts: two tetrahedra, plus one smaller cube. I made it using Stella 4d: Polyhedron Navigator, which you can try for free at http://www.software3d.com/Stella.php.
