# My 2023 Birthday Star

Today is the day I turn 55, so here is a 55-pointed star to mark the ocassion. It’s composed of eleven five-pointed stars, which works because (5)(11) = 55.

# Tens

This started with a ring of ten {10/3} star decagons, and then proceeded from there.

# Two Mandalas (from 2013)

I found these on Facebook, and could find no evidence that I’d ever blogged them here — so here they are. The first one is based on the number nine, while the second is based on fifteen.

# A Mandala Centered on a Regular Dodecagon

In addition to the central dodecagon, this mandala has two rings of squares, one of equilateral triangles, a ring of rhombi, another of regular hexagons, and, finally, a ring of equilateral decagons.

# My Birthday Star for 2022

I turn 54 years old today, so here is a 54-pointed star to mark the occasion. The nine repetitions of the six colors of the spectrum work because (6)(9) = 54.

# Eleven Times Two Times Three is Sixty-Six

The pink hendecagons are regular, and there are twenty-two of them.
