Kaatskill Kaleidoscope, New York

A former grain silo has been converted into the world's largest kaleidoscope, part of the newly renovated Catskill Corners complex, designed to attract tourists. A projector at the apex of the 37-foot tall silo projects images, multiplied by a set of mirrors, onto a screen that hangs above the viewing area at the base of the silo. The kaleidoscope is across from a zen monastery.
