The Penrose tiling pattern is a type of quasicrystal, which means that it has an ordered yet never-repeating structure. The pattern, composed of two shapes, is a 2D projection of a 5D square lattice.

Another quasicrystalline pattern (known as a Penrose pattern) in perforated metal film used in a University of Utah study showing it is feasible to harness terahertz radiation for use in superfast ...
