LINE DESIGNS FOR THE COMPUTER - Jill Britton
http://www.camosun.bc.ca/~jbritton/string_art/
In the first edition (1989) of his popular book "Curve
Stitching," John Millington included programs for the
classic Spectrum computer that created line designs similar
to the curve stitching designs in the book. Britton's web
page "Line Designs for the Computer" includes a JAVA
emulator that runs all 33 of the Spectrum programs on-line.

After three-dimensional deformation, the planar system
generates a regular, dynamic, geometrical construction.
