Yehuda Katz of Israel developed this project in MSWLogo. Now with our Math Cats MicroWorlds version, you can control four variables and see how many different "robes" you can create.
(The project uses x and y coordinates, but other than that, we feel sort of like the wizard in The Wizard of Oz as he begins to sail off in his hot air balloon, apologizing: "I don't know how it works!" We adapted it and love playing with it, but we don't know how it works! Perhaps if you read the procedures you can figure it out!)
