Twenty Hexagons with Heptagrammic Designs

The design on the hexagons appeared in the last post here, and was created using Geometer’s Sketchpad and MS-Paint. After that, I used another program, Stella 4d, to place these images on the hexagons of a truncated icosahedron, render the pentagons invisible, and create this rotating .gif file.

Stella 4d may be tried and/or purchased at http://www.software3d.com/stella.php.
