"The film was made using principles derived from Stephen Wolfram’s work on cellular automata (A New Kind of Science) to determine the content or colour of the shots, their duration, and the time of their appearance: the palette of effects, and their rhythmical development (from the simple alternations with which the film begins to the complex dynamic structures of its later parts),is entirely the result of computational processes that model natural events. John Cage instructed us that art should imitate nature in its manner of operation; I have tried to take the lesson. The music was composed by Colin Clark, using related principles".
