David Phillips – Opponent Drifting Heads in a tessellation
Country: UK
Author´s description: A moving object, seen against a stationary background, can sometimes appear motionless whilst the background appears to move. In this movie the viewer selects between two opposed directions of illusory induced movement of this kind. The outlines of the tessellating pattern of interlocking left and right-facing heads are stationary. Only the textures within the heads move. The textures are identical in every head, except that they are rotated 180 o in one set of heads. The heads facing one way then appear to move, whilst the other heads form an apparently stationary background. Either head may be the one selected to move, but the selection can ‘flip’.
