On a stormy sunday night on #revspace, fenrir saw the led starry sky at leds-buy, and tought it would be neat to have this in the hxx/eth0 bar. Some discussion ensued, and it was decided: we will build one.
The basic gest of the design: some microcontroller to drive the whole-shebang, a bunch of PWM controllers to take input from the microcontroller and drive the leds and presto. Aiming for about 100 RGB leds.

PWM controllers:
Some wild ideas:
- make it sensitive and react to E/M or perhaps light/IR sensors
- sensitive to sound
- web-interface
