Title: Aperiodic tilings

Abstract: There exist many patterns which can cover the plane in an aperiodic manner. Some, like the Penrose tilings, are both aesthetically pleasing and mathematically rich. In this talk I discuss constructions of such patterns, and touch on their connections to physics, topological dynamics, operator algebras, and semigroup theory.
