Spider web stitching

This project is to demonstrate how to space fill in a geometric shape using three spiders.

Spider 1 and spider 2 trace out the edge of the shape - spider 3 rushes between 1 and 2 to fill the space.

Susan Ettenheim needed a simper way to think this, without using complex maths or variables. The code may be adapted for Turtlestitch in order to drive an embroidery machine.

Developed by Richard Millwood at the Thinking about thinking about Seymour symposium at MIT on January 26  2017.
