Escher Museum

Maurits Cornelis Escher (Leeuwarden, June 17, 1898 – Laren, March 27, 1972) was a Dutch artist best known for his woodcuts, wood engravings, and lithographs, in which he often played with mathematical principles.
His engravings often depict impossible constructions, studies of infinity, and interlocking geometric patterns that gradually transform into completely different forms. Many of the worlds he sketched are designed around impossible objects such as the Necker cube and the Penrose triangle.
Famous examples of Escher's work include Drawing Hands, in which two hands are drawing each other, Sky and Water I and Sky and Water II, in which a play of light and shadow makes fish in the water turn into birds in the air,
Day and Night, in which black birds transition into white birds flying at night against a daytime landscape, and
Ascending and Descending, in which rows of people walk up and down a staircase in an infinite loop, on a construction that cannot be built and can only be drawn using optical illusions and perspective.
