I also made a 4 kilobyte "executable graphics" for #revision demoparty, you launch it, and it takes about 30s to compute this image fully procedurally https://demozoo.org/graphics/342286/
and finally my favorite event of #revision demoparty, the massive Shader Jam during H0ffman & Teo concert, we were ~32 coders from the party place or all around the world, all livecoding visuals with shaders that then are used on the big screen in the concert. It was so fun to jam with everyone to an awesome beat! https://www.youtube.com/watch?v=dSMlBgwciAk
