Turtletoy allows you to create generative art using a minimalistic Turtle API. You can only create black-and-white line drawings on a square canvas. By offering a very restrictive environment I not only hope to stimulate creativity, but I also make sure that the turtles can (at least theoretically) be plotted using a simple plotter.
Each turtle can be exported as SVG, suitable for high-res printing or a plotter.
Please have a look at all the nice turtles created by the Turtle community.
