I just published my Processing.org based Led Matrix controlling software. As a video says more than 1000 words, check out:  http://vimeo.com/27453711.

The software is using alot of processing libraries (Network, PImage, PApplet...) and is published on GitHub:  https://github.com/neophob/PixelController
