If I recall correctly, this is my first attempt at combining this ("Popcorn") rendering method:

popcorns.htm

...with drawing a mandelbrot set: http://en.wikipedia.org/w iki/Mandelbrot_set

Obviously, it came out rather noisily and generally not-popcorn-looking, but it's still pretty nice imo.

Entirely made in Actionscript 2.0. :)
