Peakcock is a computer algorithm-based pattern generator thats apart of the Aviary too suit. Incase you havent heard about Aviary, its a suite of web-based design apps.

In this example, Peacock is used to create "microplanets," which are then laid out and blended into a peaceful sky seen in Phoenix, Aviary's flash image editor. If you can stand the music, the teaser is quite amazing and looks fairly easy to use. Hopefully it wont be a sluggish as most online flash apps are these days.
