This reminds me of a project I found by Antirez (the creator of Redis) recently called shapeme: https://github.com/antirez/shapeme - which uses simulated annealing: https://en.wikipedia.org/wiki/Simulated_annealing to approximate an image using triangles. It took me down a really interesting rabbit hole: "The name of the algorithm comes from annealing in metallurgy, a technique involving heating and controlled cooling of a material to increase the size of its crystals and reduce their defects."

I thought it was really interesting that a useful algorithm like this was created and possibly influenced by a natural process. I wonder if this repo uses the same type of algorithm?
