Dutch artist Maurits Cornelis Escher explored the notions of symmetry and infinity and depicted visual paradoxes and impossible worlds through his art. He worked extensively on regular divisions of the plane, also called tessellations, which are arrangements of closed, interlocking planar shapes which cover the whole plane without any gaps. Escher distorted basic planar figures such as triangles, squares and other polygons into organic forms to construct his tessellations. Even though he was not mathematically-trained, Escher displayed a keen intuition and creativity which appeals to mathematicians and non-mathematicians alike.
