Seven Rainbow Polyhedra
These were made using Stella 4d, which may be tried for free at http://www.software3d.com/Stella.php.
Two Polyhedra Featuring Regular Pentadecagons
This polyhedron has 92 faces: twelve regular pentadecagons, twenty equilateral triangles, and sixty isosceles triangles, each with a vertex angle of ~42.5°. Its first stellation appears below. Both models were created using Stella 4d, software you can try for yourself … Continue reading

Four Polyhedra Featuring Enneagons
Enneagons are also called nonagons; they are polygons with nine sides. I used Stella 4d to make these four rotating polyhedra, and you may try this program for yourself at http://www.software3d.com/Stella.php.

Tessellation of Triangles and Pentagons
Alternately, this can be seen as a tessellation of hexagons and enneagons. Which do you see?

The C320 Fullerene Polyhedron
The duals of the geodesic domes are polyhedra with hexagonal and pentagonal faces. This particular one has 320 vertices, with those vertices representing carbon atoms. Here is C320 as a polyhedron. The next image shows this molecule as a ballandstick … Continue reading
