Escher art work tessellation. Love the colours and the construction of this!
Le monde étrange de M.C. ESCHER
M. C. Escher made a lifetime study of patterns and tilings, often, as here, with strange symmetries (starfish and seashells -both bivalves and gastropods). Escher was clearly delighted that a 5-symmetrical animal existed, and determined to overcome the mathematical impossibility of tiling a plane with fivefold symmetry. So the starfish fit into a rectangular pattern, and they form junctions at which either three or four animals touch arms.
