Diving Beet
Diving Beet is a port of Falling Turnip from Haskell to Futhark and Go. It is a physics imitation that uses cellular automata to implement fascimiles of gravity and (al)chemical interactions between various elements. For example, water plus fire gives steam, lava melts sand and metal (the latter at a slower rate), plants grow into water, etc.
You can look at a video of it in action - note that the choppiness (especially near the end) is due to the screen recorder not being able to keep up (it runs out of memory and starts writing to disk).
Usage
