This is image great- makes me think of a nebula. A bit of a critique- there perhaps should be just a few 'flares' of brighter spots along the fractal lines away from the main fractal images, and perhaps a few slightly more shadowed parts in the main fractals lines in their cores. It show more of a sort of pulsing in power, just as our sun has sun spots and solar flares via the magnetic forces that it generates, hence creating brighter and darker spots on its surface. But that's just my opinion.
I also remember seeing a NOVA program on fractals, and have thought they're neat. Could you do any more like this or different but still using fractals as the subject matter?
