Milk Pixel is essentially a giant, interactive, 8x8 Red Green Blue LED array with each led pixel placed inside a plastic milk bottle. The textured plastic of the bottles diffuses the lights from the leds nicely to give some interesting colour combination.
The patterns of colours are generated from webcam and microphone input as well as number of manual controls. This means that the system responds to motion and sound. During the weekend the array was feeding off live musicians, projected films, games of tambourelli (badminton with tambourines) and anyone who happened to walk by during quiet moments. The Audio Visual driver software was written entierly in Processing. In the above photo the green parts of the array reflect movments of the brass instrument and player.
