The term “mathematical art” usually conjures up just one name–that of Dutch graphic artist M. C. Escher (1898–1972). Many people are familiar with Escher’s endless staircases, hyperbolic tilings, Möbius ants, intricate tessellations, and other creations. They may also be aware of the intertwining of mathematics and art during the Renaissance, with the development of perspective painting and eye-teasing stagecraft.
