Inspired by Stan Brakhage’s films and writings, he made his first films in the late 1960s, evoking a contemplative mood. He then began making self-reflexive pieces that explore the nature of the film materials and how the medium constructs illusions of movement, depth and presence, using found footage, as in Seashore (1971), Watching for the Queen (1973), Surfacing on the Thames (1970) and the often screened Variations on a Cellophane Wrapper (1970).
