Looks to me like it's trying to generate some sort of Buddhabrot, or possibly the anti-Buddhabrot from this page: https://en.wikipedia.org/wiki/Buddhabrot https://en.wikipedia.org/wiki/Buddhabrot Actually now that I look at it I think it's the combination of the two. Basically, take a grid of points and iterate them through the Mandelbrot function, plotting where they land at each iteration. (The Buddhabrot discards all trajectories that don't escape. I don't think this one does.)
