8 square waves and phase locked blue light

this was the second and shortest piece i performed in the algorithm stage at glade 2007. lasting about 25 minutes each speaker played a square wave with varying frequency, lfo>frequency and pulse width. the brightness of the light was locked to the lfo which also controlled the frequency of the square wave. i controlled the phase of the lfo, which had a nice acoustic effect.
