An Offspring of a Dodecahedron and a Tetrahedron

To make this polyhedron, I first changed the symmetry-type of a dodecahedron from icosahedral to tetrahedral, then stellated it twice. This was done using Stella 4d, a program you may try for free at http://www.software3d.com/Stella.php.

A Hybrid of the Tetrahedron and the Great Dodecahedron

I made this by stellating a dodecahedron repeatedly, but doing so with Stella 4d, the polyhedral-manipulation software I use (available here), set to use tetrahedral symmetry, rather than the higher-order icosahedral symmetry (which I often call “icosidodecahedral” symmetry) inherent to Platonic dodecahedra.

The same polyhedron appears below, but with the coloring-scheme, rotational direction, and rotational speed all set differently.
