This year marks the 50th anniversary of the Guggenheim Museum in New York, a space known for great art exhibitions and for being a work of art itself, the iconic structure having been designed by Frank Lloyd Wright. It’s also popularly used as a movie set. To mark the historic occasion, the museum commissioned some 200 artists to create speculative reinventions of the building’s interior space, treating the vast inside expanse as a brand new canvas. The exhibit, fittingly titled “Contemplating the Void”, began this past Friday and runs through 28 April. You can view an online version of the exhibition here and the few samples below give you the idea of what to expect from this intriguing project.
