Penrose star. At the University of Oxford, Roger Penrose investigated sets of tiles that were not square in shape that would force non-periodic tiling. He found a set of six tiles in 1973 (Figure 1), and in 1974 found a set of four tiles. Soon after that he found a set of two tiles that would force non-periodic tiling. Penrose tiles can be pairs of several different shapes, though the two most interesting, and most often studied by John Horton Conway, are those depicted in Figure 2b, known as “darts” and “kites.” #Islamic_art_design #quasicrystals
