It’s a Party in America . . . Tax Refunds Arrived!


Our federal tax refund arrived! Whoo-hoo! We get back money which was ours all along, but was on loan to the government, interest-free . . . hey, suddenly this deal doesn’t sound so great after all . . . .

A Great Rhombicosidodecahedron Inspired By David Bowie, As Ziggy Stardust

Ziggy's Trunc Icosidodeca

I made this with Stella 4d, which you can try for yourself at this website.

Cluster of Six Rhombicosidodecahedra

Augmented Cubocta

To make this cluster, start with a cuboctahedron, then augment each of its square faces with rhombicosidodecahedra. Although the cuboctahedron has cuboctahedral symmetry, this cluster does not — rather, it has tetrahedral symmetry. I created this using Stella 4d, which is available here.
