### ABSTRACT

Aesthetically appealing patterns are produced by searching a class of
nonlinear
maps for chaotic solutions and then transforming the coordinates so
that
the resulting strange attractors are contained within a sector of a
circle,
which is then replicated at various angles to produce images that
combine
the symmetry of the resulting displays with the fractal nature of the
underlying
attractors. Sample images, computer code
in
BASIC, and suggestions for enhancing the quality of the images are
given.
