two transparencies with simple black and white patterns are moved by hand to create
visual interference patterns–a moire effect–that is translated into sound as wave-shaping
distortion: as the interference pattern becomes more complex, harmonics are added to the sound,
and as the visual pattern becomes simpler (separates into lines) harmonics are subtracted,
leaving a pure tone.
