I revisited a project written in 2001 and completely rewrote it using Processing.

The main improvement is that every cloud generated is a “good cloud.” What is a good cloud? Puffy and billowy. The original version of the program generated a bad-looking cloud just as often as it produced a good-looking one.

Each of these clouds grows organically from a small seed. The animation is quite nice to watch in real-time but the speed slows down once the complexity starts to rise.
