Via JRuby and Processing

WishyWorm

This one has a long lineage: It was originally adapted to Shoes in Ruby, from a Python example for Nodebox, and then, now to Ruby-Processing. For fun, try running it via jirb, and playing with the attr_accessors, as well as the background. This example now demonstrates the use of the control_panel. -- omygawshkenas
