C, O, N, S, T, R, U, C, T Peter Gidal, 1974

Labour is ostensibly the subject of this film that observes a glass window being installed. C, O, N, S, T, R, U, C, T comprises five layers of optical superimposition a multiple, kaleidoscopic perspective that collapses time: the past, present and future of every shot are simultaneously visible within the same image. Gidal presents film itself as a result of labour; a construct.
