I contracted for them a number of years ago... probably one of their biggest early shows for Arcade Fire... to address sustainability at the time, they had a microphone inside their devices. At the end of the show, they sent a special command that switched it over into "color organ" mode so you could hold it up to your stereo at home and see a trippy light show! (I wrote the audio-to-trippy rgb led code). It was cool, but even better they're re-using them now. It is a great little company in a huge old industrial factory in Montreal. Hi, Vincent!
