In 1987, COMPUTE! had an article called "Fractal Mountains for Amiga" that had a program in Amiga Basic for, well, generating fractal mountains.
Over the winter break I kinda fiddled with it a bit and started rewriting it in Go. Anyway, I couldn't sleep tonight and so I actually got it working.
So, I give you: Fractal Mountains for Amiga...in Go! The algorithm isn't 1:1, but it's pretty close.
