Recently I made several tiling images using regular heptagons or 14-gons etc.

Yesterday I noticed the happy coincidence:
9² = 81; 8+1 = 9
8³ = 512; 5+1+2 = 8
7⁴ = 2401; 2+4+0+1 = 7
Happy near year all!

See for a festive two-to-one star dissection. Merry Christmas, everyone, or whatever your appropriate seasonal greeting might be!

At Christmas Eve, I make images with reference to ENWP"Aleister Crowley's rendition of the Unicursal Hexagram, the symbol of Thelema"

"SuperTux" (a Super Mario Bros alternative) | a new release out.

A totally free and open source platformer inspired by original Super Mario Bros is still chugging along.

A rather nice game especially (?) for younger audience. It's free after all, why not give it a go! 🙂
