M. C. Escher "Are you really sure a floor can't be a ceiling?"

Maurits Cornelis Escher 
Escher uses math in his art, especially with his tessellations that are shown here. Tessellations specifically consist of closed shapes that cover the plane that do no overlap and usually don't have any gaps. The use of math was what helped Escher be able to obtain the amazing work that he is so famous for.
