Penrose P3 Tiles

Penrose tilings cover a surface in a pattern with some remarkable properties: they are aperiodic, have 5-fold symmetry, and are self-similar. There are several variations of Penrose tilings--this Thing contains the two tiles needed for the rhombus (P3) tiling.

The edge of each tile has either a notch or a protrusion, which is either round or triangular. These notches and protrusions keep you from creating a repeating pattern when tiling. Round notches need to be lined up with round protrusion
