Adapting the principles that have evolved in the development of heraldry to current needs, an algorithm was developed to aid in the description of graphic designs. It provides an efficient method of describing trademarks, logos, and other designs so that they can be found quickly using mechanical searching techniques. (26 references) (EAM)

Discussed are three examples of computer graphics including biomorphs, Truchet tilings, and fractal popcorn. The graphics are shown and the basic algorithm using multiple iteration of a particular function or mathematical operation is described. An illustration of a snail shell created by computer graphics is presented. (YP)
