Pentagonal Penrose Tile Set Reclaimed Wood Laser Engraved and Cut Wall Art or Crystal Grid CA made conflict-free metalsThis wall art or crystal grid is based on the Penrose Tile Set. In 1973 Roger Penrose, a mathematician, found a set of six tiles that force aperiodicity, or non repetitive tiling. Later, in 1974, he was able to reduce the set to two tiles. The shape of a pair of Penrose tiles can vary but the most common are the kite and the dart. These tiles are derived from a rhombus with angles 72 and 108 degrees. The Penrose Tiling Set solves the issue of how to
