I've been very low on free time recently, so I've been goofing around with fractals.
Funny that, me too (Julia sets; f(z) = z^2 + c through to f(z) = z^5 + c and so forth). I've been working on making a Android live-wallpaper out of them. Although I think your representation of them is far, far ahead of mine. The colour schemes look beautiful and almost other-worldly. In fact, I'll delve deeply into your code over the next few days and try to work out how you've done it.
Well done, it's very impressive.
