Umm... uses a custom pixel bender filter to do the job really fast... (essentially, its a cellular autonoma for those of you how know about them. Its just on a sort of analog basis rather than a digital on/off one)
The initial effect is good but it sort of degrades to color noise after a bit. I might add to it later. But the most i seem to be able to get out of it is this sort of noise pattern which is frustrating. I had visions of spectacular intricate patterns developing etc.
