Set of 8 (2 sets of 4 patterns) coasters or tiles, in the shapes of Penrose tiles. (Penrose tiles form an infinitely non-repeating pattern out of 2 basic shapes.) Intended for laser cutting and engraving. Pieces are irreglar, but roughly between 4.4–6.6" diameter. Due to the nature of Penrose tiling, there's no one way to fit them together.
Please note, the pattern isn't designed to tile into an expandable, solid surface of Penrose tiles. Rather, the tiles are configured to lock together into interesting compositions that emphasize a dynamic, asymmetrical aesthetic.
