The peripheral drift effect is applied to a random pattern to give the illusion of motion in different areas of an underlying figure, in this case a star. The random quality of the pattern tends to minimize interference between the elements of the image that generate the illusion of motion and the interpretation of the overall figure. The technique could possibly be used to “animate” illustrations of phenomena such as fluid flow, flux lines, or weather patterns.
