Abstract. We use photographic slides of aperiodic Penrose and Ammann tilings as two-dimensional diffraction gratings to describe and demonstrate some important basic properties of two- and three-dimensional quasicrystals.

Key Words: Laboratories and Demonstrations; inorganic chemistry; quasicrystals; Penrose tiling; Ammann tiling; diffraction; Fibonacci lattices; crystal symmetry; crystals
