Leds make no sound

A few years ago there was a led demo (according to Germans: Ledlaufschiftanzeige) at the Siliconvention. We even won a Nintendo64 with it but they forgot the keyboard... Easy obcessed as always I can't let the leds go.

This time I've tried to research the posibility of replacing comming lighting by leds.

• Leds in aquariums
• Leds in the livingroom
