This clip describes the re-production of sound on films, using photographic processes. Sound waves are converted to varying voltages, which affect varying amounts of light, which is then projected and photographed onto the films optical sound track. This is how motion pictures sound tracks have been reproduced in cinemas right up till the 21st Century, hence printed digital sound tracks have become more common.
Here Soviet composer Arseny Avraamov draws wave forms with paint on paper and then films them onto the optical track with amazing results.
Godfried Toussaint writes this neat paper on transcribing and generating African music rhythms via Euclidean geometry. Euclidean geometry is taking a set of simple, known elements and producing new elements from these. Applied to music he devises algorithms to generate permutated rhythms.

Wellington moving image artist Erica Sklenars and musician Dan Beban were surprised to discover that they were each, independently, using saxony wheels as a basis for moving-image and musical devices respectively (originaly these wheels were designed to spin thread into yarn). Inspired by this link they formed ‘Sign Of The Hag’ and began performing live moving image and sound looping together.
