During 2009 the Guggenheim Museum celebrated its 50th anniversary. The museum commissioned nearly 200 artists, architects and designers to imagine their dream interventions on the most significative space of Frank Lloyd Wright’s building, the central void. The artwork for every design is now available through a charity auction. You can bid for your favorite one right here. “Contemplating the void” (check some of the designs in ArchDaily here) will be on exhibit at the Museum until Apr 28th.
