    Abstract: A method of creating apparent motion on a two-dimensional surface, the surface being illumination responsive to a directed moving reference of light source. The method comprising the steps of devising on a tracing sheet at least one pattern of apparent motion to be created on the surface. Dividing the pattern into a plurality of discrete and spatially related zones. Next a direction of apparent motion to be created within each zone is determined. The pattern and zones thereof are then transferred onto the surface of a light responsive deformable material. On the surface is found a plurality of grooves corresponding to each zone. The grooves in the direction of apparent motion are progressively angled relative to the directed moving reference of light source from about 90 degrees through about 180 degrees.
