About Turtletoy

Turtletoy allows you to create generative art using a minimalistic JavaScript Turtle graphics API. You can only create black-and-white line drawings on a square canvas. By offering a very restrictive environment, we not only hope to stimulate creativity but we also make sure that the turtles can (at least theoretically) be plotted using a simple plotter.

You can read the Turtle API reference first or directly start writing your turtle here.

Each turtle can be exported as SVG, suitable for high-res printing or a plotter.
