scaffold for the Turtle Art Tiles Project

I've developed a sequence to help students towards interesting designs for their Turtle Art Tiles Project. This turned out to be a combination of some shapes from Barry Newell's old booklet and some others I discerned from the images in the Project itself. The idea is to start students on simple shapes and then show them hints to some pathways to more complex shapes.
