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

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.

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...
