I'll release PixelController v1.31 soon, fancy new features: -Wireless PixelInvaders Panels (using ser2net and a RPI) -OSC Generator: use Processing (or any tool you like) to send images to PixelController. I included some examples how to use a MS Kinect and how to stream live video feed from your Android phone to the PixelController software.
After PixelController Beta 18 I finally released the final version. I even created a short rough cut video that will show you, what PixelController does.
I made with some friends an Arduino based Stage Design: eight 80cm high wooden letÂters and 110 Led modules controlled by a Processing application. I released the Arduino and Processing Code on GitHub and wrote about the project on my blog: http://neophob.com/2012/11/kalikut-now-stage-design/
<shameless advertising> You could also use some LPD6803 based LED Modules together with your Arduino/Teensy board here http://pixelinvaders.ch/?page_id=390 </shameless advertising>
And btw, I just uploaded the v1.3.0 Beta 5 release (latest Beta Release), contains some fixes and more device support.
