Artist M.C. Escher spent a lifetime distorting perspective

The late Dutch artist M.C. Escher is perhaps best known for his tessellations that fool the eye, like “Sky and Water I,” where birds in the air trade off negative space with fish underwater. But there are 200 lithographs, woodcuts and drawings on display in the biggest-ever U.S. exhibit of Escher’s work at Brooklyn’s Industry City. Hari Sreenivasan went on a tour with the exhibit's manager, Johanna Guttmann.
