"Touching the Void": Radical Reinventions of Guggenheim New York

This year marks the 50th anniversary of the Guggenheim New York, designed by Frank Lloyd Wright. It's a legendary building, and the cavernous central atrium is one of the most famous spaces in modern architecture. It's also a bit of a blank canvas, only rarely filled out with art or installations. For Touching the Void, a new exhibit opening this Friday, the Guggenheim asked over 200 artists and architects to propose "dream interventions." Here's a sneak peak.
