By the mid-1950s some of Heath?s contemporaries were beginning to experiment with three-dimensional constructions using industrial materials. In around 1954 Heath himself began to explore this avenue with plastic reliefs of which this work seems to be the only surviving example. `Light Screen? does not resemble the reliefs by Victor Pasmore or Mary Martin but rather recalls those made by Hungarian-American artist Laszlo Moholy-Nagy. Its planes, which seem to advance from the background through the foreground surface into the spectator?s own space, also resemble those in the paintings of Czech abstract artist Frantisek Kupka of around 1912 which Heath admired. The original relief was made in 1954 but due to damage Heath remade it in 1982.
