Blinkenwall..
- is the wall between our mainroom and the library
- in this wall are 9x5=45 glassbricks installed
- next to every glassbrick there is one RGB-led with a pretty neat chip attached
- these presoldered boards are called Shiftbrite
- they are currently controlled from an arduino this may change soon for something with more computational power :)

- Metaz - arduino library software for shiftbrites
- Wizard23 - help with electronics, basic software setup
- Overflo - electronics, soldering
- .. lots of guys playing around
