Barcodes is a film based on the manipulation of a barcode to play tonal ranges. The barcode was copied onto a transparent sticker, then glued to the film up to the film's soundtrack. The barcode then emits a sound as it passes in front of the photocell. By sticking on a barcode of different sizes, the barcode plays on a two-octave scale (from low C to high C). Funnily enough, we can also see how volume varies with line contrast. The greater the contrast, the higher the volume.
