Grainface laptop performance

Here's a video of a german laptop ensemble giving a performance.
The music is quite 'ambient' with long sustained tones and then short percussive elements introduced throughtout - there's also some vocoding going on.
Musically, it's not everyone's cup of tea and the performers do look like they're taking themselves a little too seriously at times. But they use wii-motes as gestural input devices to control the sound and the link between their actions and the sounds being generated is pretty obvious - so worth a look...
