Transparent vinyl. The records come with white inner sleeves in two separate white standard outer sleeves, sealed in transparent foil envelopes.
"A record onto which an empty groove has been cut is scanned visually. Two versions of this image, differing in magnitude and off-center position, are then transferred physically into the grooves of two new records, 1 and 2. The images of 0 then appear visually on the surfaces of 1 and 2.
The imaging has been achieved by modulating the amplitude of a carrier (sine) wave with the output of a brightness sensor. The sensor moves over the image of 0 in spiral circles, registering the recesses and elevations of the record's surface as represented in its scan. The sensor's trajectory exactly matches the vinyl groove of a 12" record, into which the resulting audio content is cut. The offset images of 0 then miraculously reappear on the new records' surfaces.
On playback, the modulated carrier wave can be perceived: a sinewave at 1760 Hz (a frequency chosen for balancing image resolution with vinyl's tendency for geometric distortion) is probing the projected object like a sonar.
Cutting the audio files to 12" records will reproduce the encoded images."
