ABSTRACT:
A multi-dimensional image is obtained in a substantially flat surface covering by aligning the platelets of a platey material in the optical surface of the surface covering parallel to the exposed surface of the surface covering and realigning predetermined platelets to a predetermined angle with respect to the original alignment. The platelets can be realigned by pressing a gelled transparent or translucent element into the platey material containing layer or by mechanically embossing the platey material containing layer.
