A nice change from most of the truly random-type FX visualizers. A few tweaks and I had a nice "Alchemical Flame" going. Only wish that the high intensity response could be channed into either another color (as opposed to "white") or, perhaps even a new shape geometry? Perhaps this could run 90º to the original, or cross split, or even more exciting, into a circular or polygonal shape.

How about adding the visual equivalent of a Leslie rotating speaker effect...for the eyes?

Anyway, a great idea, well implemented. I did have one crash while modifying the settings, though. No big deal I guess. Now...to...get back to staring into the flame!
