The "Relativity Room" is an interactive part of a major exhibition of the work of Dutch artist M.C. Escher.

Escher is perhaps most famous for his optical illusions that show seemingly logical scenes that are actually impossible, but he is also known for his intricate pattern work of animals and objects.

Over six decades, until his death in 1972, Escher created 448 lithographs, woodcuts and engravings and more than 2,000 drawings and sketches.

The Italian art exhibitor Arthemisia, in collaboration with the M.C. Escher Foundation, produced and organized this presentation of 200 of his works from international collections at Brooklyn's Industry City. It's the largest M.C. Escher exhibition ever shown in the United States.
