soundresponsive

boris.kopeinig.net | club.ware - infrasemantic sensory modulation, tmp sys, blink or VSP, visual (self)stimulation pattern, sub stim

soundresponsive, 2003, visual system based on realtime FFT audio analysis, frequency bands are selected by random values, so it never worked like a car radio equalizer display.
