It's been interesting playing around with Aphophysis and a few other apps for fractal generation. Quite surprising the kind of variety you can achieve- i only really touched the tip of the iceberg (Ha!) with Flurry, and i've got a load more in the works.
The trouble i've got now, of course, is with rendering times. Rendering Flurry took 3/4 of an hour on my fairly modern machine (Only 7 years old) and that was at pretty low resolution. It looks fine, but for prints it's not enough, and cranking the quality/res results in day or week-long renders. Not great when I need my machine.
If only you could just save a partial render to carry on late
