There's a Powder Toy subcommunity which focuses on building computers in-game. The state-of-the-art (subframe) involves exploiting particle evaluation order to create CPUs that can run at 1 instruction per frame. I even wrote a Forth implementation for such a 16-bit 8K RAM computer. Good times. [0] https://github.com/siraben/r216-forth https://github.com/siraben/r216-forth
