M. C. Escher is known for his repeating patterns of interlocking motifs, tessellations of the Euclidean and the hyperbolic plane and his drawing representing impossible figures. Without having any mathematical knowledge, he managed to represent many mathematical concepts belonging to non-Euclidean geometry and many of his drawings are used by mathematicians to illustrate examples.

These hyperbolic geometry pieces created by Escher, in my opinion, look like never ending tessellations. As you can see on each of these pieces below, the objects get smaller and smaller the closer you get to the edge of the circle and infinitely continue. Very interesting style of work taken on by Escher.
