WTF
Juli, pwnschlager, wirehead and I are going to build an LED project for Die Schmiede. We use this page to organize the project.

| Solder power lines from power supplies to LED-strands | ? | ? | ? |
Code
I hacked wmgui (part of libcwiid) to output MIDI events and wrote a simple visual that slides over a large image depending on events, always only showing a portion of the image.
