We just got back from a vacation to Texas. One of the fun things we did there was visiting Inner Space Cavern in Georgetown, where I took these pictures.
A Dodecahedron, Encased By Stars
I made this using Stella 4d, which you can try for free right here.
Two Polyhedra Derived From an Enneagonal Prism
I made these using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.
A Three-Part Polyhedral Compound Derived From an Enneagonal Prism
I made this using Stella 4d, which you can try for free at this website.
Both of these prisms have 28-pointed stars as bases. I made them using Stella 4d: Polyhedron Navigator, which you can try for free right here.
A Ring of Fourteen Heptagonal Prisms
I made this using Stella 4d, which is available here.
A Tessellation Featuring Regular Heptagons, Regular Hexagons, and Many Irregular Polygons

The Twenty Triangles of an Icosidodecahedron
I made this with Stella 4d, which you can try for free here.
An Icosidodecahedron Variant
I made this using Stela 4d, which you can try for free here.
Three Views of a Modified Great Rhombicosidodecahedron
To make these using Stella 4d (available here), I started with the great rhombicosidodecahedron, then used the “morph duals by expansion” function on it — twice. Here’s the result, shown with coloring done by face type.
The next one has faces colored by number of sides.
Finally, here’s one shown in rainbow color mode.
