Arbitrary Logic

I made my first computer film in 1969 when it took 9 months to make 8 seconds of animation using the largest computer in Britain. I did not make any more computer work until cheap home computers, Sinclair Spectrum then the Atari, became available in the early 1980's. I made a number of works using the Atari where I wrote programmes from scratch developing systems where the same programme and numerical values generated modified picture sequence and colour values and also created the sound via MIDI and a synthesizer. Arbitrary Logic was the first of these. In its original form it was an interactive work "played" directly from the Atari and projected onto a large screen. The first public performance of it was at the Osnabrück festival and the original programme had the working title Osnabrück. The version now screened was transferred to video for a Channel Four TV work called Sketches for a Sensual Philosophy. (Malcolm Le Grice)
