I ran into this on Facebook, where I posted it in 2011. That was the year before I started this blog.

My Birthday Star for 2020
This is the day I turn 52 years old, and I’m marking the occasion with a 52-pointed star. This particular star is a compound of four thirteen-pointed stars, each shown in a different color. This works because (4)(13) = 52.
The 5/2, 5/2 Duoprism
I made this duoprism, a four-dimensional polytope, using Stella 4d. You can try this program for yourself, free, at http://www.software3d.com/Stella.php.

Yellow Star Tessellation
In this tessellation, the hexagons, pentagons, and squares are all regular. The irregular polygons are equilateral decagons, as well as equilateral and concave tetrakaiicosagons.

My 2019 Birthday Star
I was born 51 years ago today. To mark the occasion, here’s a 51-pointed star. It’s made of {17/7} heptadecagrams repeated 3 times, and with their edges extended as lines, in three different colors. This works because 51 = (17)(3).
