Hanging Disc Toy by Li Yuan-chia (1929-1994) in the Tate Modern Gallery, London, England. Purchased 2004. T11870. Li made works that consisted of large, colourful metal discs with magnetic wooden blocks, each carrying a photograph. When this example was originally put on show (1980), the spectator was invited to move these blocks around the discs but unfortunately the work is now too fragile for this to happen. As the discs are suspended, the slightest air movement causes them to slowly rotate, perpetually changing the aspects on view.
