The “snowflake” dodecagons are equilateral, and resemble star hexagons — but the resemblance is close, not exact.

Great Circles

These great circles are all in the reflection planes of an icosidodecahedron, but that polyhedron, itself, is invisible here.

Great Rhombcuboctahedron with Red and Blue Mandalas
Image
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.
