A sketch for recreating and plotting a blatant copy of Georg Nees's early work in computer generated art. It contains a "symbol" class that lets you define your own symbols instead of square boxes.
See the output here: http://www.tobiastoft.com/posts/an-intro-to-pen-plotters (scroll half way down the page)
Warning: The code is only sparsely commented. Shame on me.

Forked by Pierre and heavily modified. The code now no longer drives a plotter but creates an SVG with the result.
