I know FF is not the ideal place to try this intensive recursion, but I thought there might be a way to fake it. Trying to get reasonable erosion can lead one to either the noise based approach, or a sequential one. Having roughly licked the former smile:D , I thought I'd share my attempt at the latter and ask if anyone has any suggestions on how to improve it.

Let me know if this is more of what you were looking for. I modified both Cells, but nothing else. If not... smile:bunny:

Ok, got it. Both your version and my futile attempt look more like reaction diffusion. I know I had seen this structure before, it is very similar to a dendrite fractal.

Cool article, and many applications, yep. Here's a nice swift Mathematica implementation FWIW:

The Mathematica demo is helpful. I played around, with loops and Bomber+, not much success. Anything I tried past 5 iterations slowed it down all the way...
