A Polyhedron With Eighteen Faces and Tetrahedral Symmetry

This polyhedron’s faces are six rhombi, and twelve kites. I came across it by modifying the truncated tetrahedron, using Stella 4d: Polyhedron Navigator. You can try this software for free at this website.

A Spiky Symmetrohedron

This was a normal symmetrohedron, until I augmented its trapezoidal faces with pyramids. I did this using Stella 4d: Polyhedron Navigator, which you can try out for free at http://www.software3d.com/Stella.php.

A Zonohedron Based on the Octahedron

To make this using Stella 4d (available here), I started with an octahedron, and then performed a face-based zonohedrification on it — six times.

A 56-Faced Polyhedron Featuring Eight Regular Heptagons

A Zonish Rhombicosidodecahedron

This zonish polyhedron is based on the vertices of a rhombicosidodecahedron. I made it using Stella 4d, which you can try here.

A Zonish Dodecahedron

This zonish polyhedron has 162 faces, and is based on the faces and the vertices of a dodecahedron. I made it using Stella 4d, which you can try for free at this website.

A Polyhedron With Tetrahedral Symmetry, a Dozen Regular Heptagons, and a Whole Mess of Triangles

I made this using Stella 4d, which you can try for free at this website.

An Astronomical Dodecahedron

NASA’s Artemis I spacecraft snapped this picture of the Earth moving out from behind the far side of the Moon. I put it on this rotating dodecahedron using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.
