In this relief (1963), an aluminium disc decorated with a reed pattern, rotates under glass that has been moulded with a similar pattern. The movement itself cannot be perceived. Instead the disc appears to dissolve into a rippling light and, through optical illusion, seems to be continuously reforming itself as an oval while, at the same time, remaining a circle.
Hein’s experiential, perceptual magic tricks are his vehicle for raising engagement between art and its audience. He makes work that can only be experienced through participation, expanding our notion of what art is or could be. ‘For me, the concept of sculpture is closely linked with communication… By challenging the physical attention of the viewer, an active dialogue between artwork, surrounding and other visitors is established that lends the sculpture a social quality.’
