The Australiancopyright case of Greenfield Products Pty Ltd v. Rover-Scott Bonnar Ltd (1990) 17 IPR 417 is authority for the proposition that a thing not intended to be a sculpture is not a sculpture. This seems contrary to some famous examples of sculpture, including Marcel Duchamp's 1917 sculpture consisting of a porcelain urinal lying on its back, entitled "Fountain", and Carl Andre's sculpture "Equivalent III" exhibited in the Tate Gallery in 1978, consisting of bricks stacked in a rectangle.
