Four Triangular Dipyramids, Surrounding a Common Point I made this using multiple stellations, some of them with tetrahedral symmetry, to modify the cubohemioctahedron, one of the uniform polyhedra. I did this using Stella 4d, which you can try for yourself, free, at Also, here's what the…

A Second Tessellation Featuring Regular Octadecagons, Regular Octagons, Equiangular Hexagons, and Concave Pentagons This is the same tessellation as the one in the last post, except that this one has had its colors inverted, using MS-Paint.

My 2025 Birthday Star I turn 57 years old today, so here is a 57-pointed star to mark the occasion. It's actually 3 stars, each of which has 19 points, which works because (3)(19) = 57. The individual stars here are {19/9} heptacontagrams -- a blue one on the bottom layer, with green on the top,…

Did you know that #snow is not white? If it's snowing where you are, go outside and look straight up. Against the cloudy white background, you'll see snow of a different color.

We need better, less ambiguous abbreviations for the various disorders known as "BPD." It stands for BiPolar Disorder, as well as Borderline Personality Disorder, and Brief Psychotic Disorder. #BPD Thankfully, I only have one of these. Can you guess which one?

I love that Jeri Ryan posts anti-Trump stuff on here. Even more reason to love her (in addition to the fact she played an excellent character in Star Trek)

Amen! (It must be true, if it could get an atheist like me to say "amen.")

#Neurodiversity wasn’t created as a cute euphemism. When we say “autism isn’t a disease, it’s a difference,” we’re serious. We’re finding a way to live well in this world as #autistic people. To be happy & unashamed of who we are.

A Polyhedral Journey, Starting With the Truncated Tetrahedron Here's the truncated tetrahedron. It is the simplest of the Archimedean solids. I decided to "take a walk" with this polyhedron. First, I used Stella 4d (available here) to make the compound of this solid and its dual, the Catalan solid…

This new year is the first perfect-square year since 1936, and there won't be another one until 2116. Since…
