It is the function of art to renew our perception. What we are familiar with we cease to see. The writer shakes up the familiar scene, and, as if by magic, we see a new meaning in it. - Anais Nin (Art - M.C. Escher)
M C Escher Maurits Cornelis Escher 17 June 1898 – 27 March 1972), usually referred to as M. C. Escher, was a Dutch graphic artist. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations. 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.
