A simple fractal animation I did several years ago. Also, this is where my avatar came from.
87 frames, made with Apophysis, resized and animated in GIMP. Loosely based on `MichaelFaber
's Disc Spiral Tutorial
2011/11/05 Edit: Merged first and last frames for better loop (they're 84 frames now), uploaded larger file.
2013/12/20 Edit: Finally rediscovered how I had made this years ago: the newer version is available here
