What happens when you combine 1 building, 40,000 LEDs, a couple of electronica tunes, and 4 programmers/composers? An entire building can come to life, and dance to the rhythm while accenting the melodies. Front and foreground, standing in the limelight is the Ars Electronica museum in Linz, Austria. The project was developed using a mix of Ableton Live, Max/MSP, PureData, and OSC. Thankfully, the members involved had the foresight to record the performance, and the museum can replay the audio w/ the visuals at any time. (audio starts around 20 seconds)
