Wireworld in 38 blocks! Turn on Turbomode (shift click flag) and Hold space
This is not meant for efficiency, I was simply trying to create a fully functional Wireworld in the least amount of blocks possible. @B06DAN3L2 reduced it to 36 blocks: scratch.mit.edu/projects/1263868096 Wireworld is a Turing complete cellular automata. (Although, I wouldn't call this project Turing complete, because the grid is limited to the screen.) I did some fancy things to reduce the blocks needed, like using backdrop names for the indexing instead of lists, and I made a c++ program that created 225 images, one for every pixel in a 15/15 grid, that way I can just use "next costume" to move to the next pixel. then it was mostly just down to simplifying the logic. I also made Conway's game of life in 31 blocks, Metaballs in 10 blocks, and a Scrolling platforming game in 15 blocks. :D
