A strange bifurcation algorithm from an older iterated function system of mine:

 My pseudo code is in the description:

// angle interpolates from 0...pi2 across iterations
// px = py = 0

 Anybody should be able to reproduce it on their end. Right?
 It's all 2d, but has a 3d vibe! Nice.
 Any thoughts?

It looks like a fractal version of an optical illusion of whether a cylinder (with the fractal on it) is rotating in one direction or the other.
