A Tessellation Featuring Regular Hexagons and Two Types of Rhombi

This tessellation is made of blue regular hexagons, as well as rhombi containing 40 and 140 degree angles (red), and rhombi containing 80 and 100 degree angles (yellow).

Snowfall in Blue

Like much of America, we’ve had a lot of snow lately, with more on the way. Making the piece above helped me unwind after a very stressful drive to the store and back on snow- and ice-covered roads. The car went skidding all over the place a few times, but I did make the trip without actually running into anything. I’m not going out again until the melt arrives.

We’re in a global pandemic, without competent national leadership, and American society is tearing itself apart. However, at least you get to see this cute picture my wife took of Hexagon the Cat hiding in a blanket, right?


Twenty Hexagons, Each Adorned with Images of Hexagon the Cat


I made this using Stella 4d: Polyhedron Navigator, a program you can try for free at this website. It shows Hexagon the Cat riding in circles on the twenty hexagonal faces of a rotating truncated icosahedron. We don’t know of a cat named Pentagon, so I hid the twelve pentagonal faces.
