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.

A Zome Construction, Mostly of Rhombi

The yellow figure is a rhombic dodecahedron, and the red pieces form six rhombi which intersect the faces of the yellow figure. There are also hypershort red struts connecting the red rhombi to each other. It’s not exactly a polyhedron, but I had fun making it. I built it using Zome, which you can buy for yourself at http://www.zometool.com.

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.

A Fifty-faced Zonohedron Which Is Also a Symmetrohedron

I created this symmetrohedron as the zonohedron based on the faces, edges, and vertices of the tetrahedron. It has fifty faces: thirty squares, plus eight regular hexagons, and twelve merely-equilateral hexagons. I made it using Stella 4d, which you can try for free at this website.
