Griselda is a small java application that outputs complex Bezier shapes in Adobe PostScript.

Originally coded in HyperTalk on an early Apple Macintosh ,Griselda began as a personal exploration of the book “Turtle Geometry: The Computer as a Medium for Exploring Mathematics” by Harold Abelson and Andrea diSessa. (MIT Press 1981).

Bezier curves are generated procedurally
using a turtle; control points are modified as sets whose angles and lengths are changed by various morph actions.

This method was devised long before filters like ‘Punk’, ‘Bloat’ and ‘Twist’ appeared in commercial drawing programs; and I'm sure you will agree the method used in Griselda is more sophisticated and allows far greater control of the bezier curve...
