The artist M.C. Escher's work often used ingenious tilings of the plane with interlocking figures such as fish and birds. Although these tilings could in principle extend forever, Escher could not show this on a finite picture. But a diagram from a paper by the mathematician Donald Coxeter presented one solution to this conundrum. We will look at the mathematics of this diagram and how Escher used it. We will also see how Coxeter produced mathematical research based on aspects of Escher's work.
