Barcodes is a film based on manipulating a barcode to play scales of tones. The barcode has been copied to a transparent sticker and then glued to the film all the way to the soundtrack of the film. The barcode then makes sound as it passes the photoelectric cell. By having glued on a barcode in different sizes, the barcode plays over a range of two octaves (from low to high C). The fun thing is that you can also see how the volume changes with the contrast of the lines. The more contrast the higher volume.
The film was shown in an installation titled "Composition for a film projector, barcode and a spotlight". The installation consists of, as the title discribes, a 16mm film projector, a spotlight and a film.
