He's the same one who helped me put together animations for my mathematics seminar in college (on a Mac II). His current work is mostly kaleidoscope images using renderings as the base, but the application supports using any image -

http://www.softpedia.com/reviews/mac/FractalWorks-Review-145285.shtmlThe animations were of the Mandelbrot and Julia sets (56-frame animation). The first was a 36-frame dive into what we called the "seahorses" (on the main cardioid in the valley of the first circle on the real axis). We call the other side of the valley the "elephants". For the Julia sets, we passed out of the cardioid's asshole on the real axis to watch the Julia set go from a rectangular blob to the disconnected cauliflower "telephone handsets" pattern. The main point of that was to show that the Julia sets are connected when the center point is part of the Mandelbrot set, or in other words that the Mandelbrot set is a mapping of the connected Julia sets. I also used Logo on an Apple II+ to render the progressions of a Koch curve.
To find the best locations for the animations, I had my Apple II+, my C=64, as well as two Apple IIe's and an Apple II GS (I think those were the models) at the college running all night plotting six images each at 50 iterations for various sample points. They were crude, but sufficient to allow me to narrow down what we wanted to do with the animations. We also created a logarithmically-based color table for FractalWorks that would let us change parameters to enhance the detail based on how deep into the set we were. Damn were those things pretty.
I really should write a new program. I've got a 3.33GHz Win7 Ultimate tower with a six-core i7, 24GB of RAM, 9TB of mostly free disk space, and VS 2010. I think that puppy could do some rendering.
