M. C. Escher

M.C. Escher (1898 – 1972) was a Dutch graphic artist known for his often mathematically inspired woodcuts, lithographs and mezzotints which feature impossible constructions, explorations of infinity, architecture, and tessellations.

One of Esher's famous work titled Relativity depicts a paradoxical world in which the normal laws of gravity do not apply. The piece of art was the source for the Illusionary maze in Labyrinth. As a result the Escher estate was given acknowledgment in the credits for the film. A copy of Relativity can also be seen hanging in Sarah's bedroom.
