Truncated Dodecahedron with Mandalas

A flat version of the mandala on each decagonal face here may be seen in the previous post. I used Geometer’s Sketchpad and MS-Paint to make it.

To place the mandalas on the decagonal faces of a truncated dodecahedron, I used a program called Stella 4d, which you may try for yourself at http://www.software3d.com/stella.php.
