Math Academy Online presents a great M.C. Escher (1898-1972 CE) site for connecting the arts and mathematics. As even Escher said, "For me it remains an open question whether [this work] pertains to the realm of mathematics or to that of art." Here you will find a biography of Escher as well as many examples of his fascinating artworks and descriptions of how these works connect with mathematics. Tessellations, polyhedra, the shape of space, the logic of space, and even the relationship of Escher's art to information science and artificial intelligence form the topics for sections of this interesting site.
