I quite like this one. The transition mask is better than my plasma one and the 3 different kinds of transitions with the color fade makes it interesting. Is it perlin noise or a fractal generated texture or something?
To be perfectly honest, I'm not quite sure.. It's something i found laying around in my code folders but knowing what kind of stuff I normally code I'm willing to bet that it's some kind of experimental noise function with some blobs and distortion

in dosbox it lagged like hell though, probably because Dosbox stopped it from getting 100% cpu power, does anyone know how to fix that?
Paul, go thru your dosbox.conf and change your core=auto and cycles=auto to: core=dynamic and: cycles=max and that should fix the dosbox problems..
