Simon, did you use the effect(just wondering)? I originally thought the same, but how about Fractal Distance or Fractal Curve Distance? Some people dont know what a fractal is >.<Fractal (Wiki this)
I did but for the people who dont it doesnt explain enough what is happening to the image enough by just saying detail or complexity. Imo
But after downloading(it does work with 3.5.3450 the alpha build, awesome ) I made this in like 2 Mins \
