A new version of FlashMandelPPC the best fractal rendering program is on Aminet into gfx/fract directory.
Gfx cards and PowerPC cpus are fully supported, FlashMandelPPC runs on MorphOS too (under WarpOS emulation) and will take advantage from next generation of amiga computers for realtime renderings even at deeper zooms with highest iterations.
Look at the readme for some FlashMandelPPC features :-)
