The design on the faces first appeared in the last post, and was made using Geometer’s Sketchpad and MS-Paint.

I used Stella 4d, another program, to put this design (as a colorized version) on the octagonal and hexagonal faces of this great rhombcuboctahedron, and then render the square faces of this polyhedron invisible. This program is available at http://www.software3d.com/stella.php.
