orologio en CB01 OFFICIAL. Brightly coloured animated drawings rotoscoped from high contrast black and white negative film of Ivor Cantrill aged 14, are integrated with the original negative and positive images on an optical printer to create patterns of black, white and colour. The film-maker reminisces about being 14 and describes the rotoscoping process. Ivor Cantrill is autistic, and his attention to detail and his preoccupation with repetition are positive aspects of his condition.
