With the piece Fourier-Tanzformation I+II mikomikona present a
physical-semiotic experiment. In this investigation, we make use
of two overhead projectors as sound devices.
To accomplish this we layer several transparencies with raster
patterns, flickering interferences are produced through shifting
of the layers. Parallel to the projection, we capture these interferences
with small b/w video cameras and transform the video signal into
acoustic events. We implement our image-sound-converter, a small
self-developed hardware device which eliminates the videos
sync signal. The spectators see the two projections of black &
white moire patterns while simultaneously hearing the sound these
patterns perform. What you see is what you hear. Fine moire lines
produce high tone, wider lines result in lower tone pitches. With
small motors we create visual and acoustic rhythmic structures.
Mikomikona is dispensing with any digitalisation. This ensemble
of analogue techniques represents an opto-electronic synthesizer
with two crossed outputs: image and sound.
