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

The Moon Unit Proposal
I propose that 384,400 km (238,855 miles), the average distance from the Earth to the Moon, be called a “moon unit.” Example: “The mileage of my car is over one moon unit.”
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.
