Photoresistor controlled quadrature gated oscillators based around quad nand gate schmitt trigger integrated circuits. 14 separate oscillators. digital processor chips misused: the ones and zeros of digital logic plugged directly into normal analogue audio equipment. variations of light and shadow from the video projection effect the photo sensor’s resistance, oscillator pitch and chaotic interactions between sub-circuits. mini camera routed through effects processor to data projector. Playful interactive instrument/installation.
