GIP: fractal colours

I thought about how I could produce an icon with the maximum number of possible colours, but in a somewhat pleasing way.

( The making of: this ended up kinda long and geeky )

So, anyway: I give you my fractal 9216-colour userpic!

And due to the fact that adjacent pixels typically have a similar colour, it even compresses fairly well. (Certainly a lot better than the random-colour userpic I also generated, based on data from random.org.)

What do you think?
