I keep going back to good old free MandelBrowser, one of the first ones I stumbled across--it's easy to learn, requires no math competency and saves pictures to PICT format. But then I see the 3D fractals that apps like UltraFractal can do.....and I want an UltraFractal for the Mac....sigh. Luc, please do post again! I'll see it tomorrow AM (US Pacific Coast Time). Gotta be something out there somewhere.
