This talk concerns a basic geometric question: can you find a shape that can cover the plane exactly twice uniformly (in the manner of a tiling, but double layered) and also three times uniformly, but which yet cannot cover the plane once uniformly? The answer is yes. If you're curious as to what the shape looks like, come to the talk.
