1997 ``Persian'' Recursion

Anne M. Burns First Paragraph: In this note we present a very simple recursive procedure that produces a variety of attractiv patterns resembling Persian rugs. Recursion, by its very nature, can lead to surprisingly complicated and self-similar patterns. The idea behind the "Persian" recursion is to start with a largee square, subdivide into four equal squares, and continue the process until we cannot go any further.
