Visit the World of Escher, a fascinating educationally based site that explores the Dutch graphic artist M.C. Escher's unique and often impossible work. From an early age, Escher was fascinated by repetition and infinite patterns. He explored with great enthusiasm the regular division of the plane in his tessellation or symmetry drawings linking math and art. Impossible buildings, spatial illusions, perspective drawings, woodcuts, and lithographs have fascinated young and old for more than half a century. A great teachers' resource. Is there another artist that links math and art like Escher? Bring your students into the magical world of Escher. Enter your own tessellation in the on-line tessellation contest, win prizes, certificates and possibly an entry into our Hall of Fame. Opinions and addition information on Escher are welcome for inclusion in the site.
