Yesterday the Guggenheim launched an online competition, Re: Contemplating the Void, to celebrate the exhibition Contemplating the Void: Interventions in the Guggenheim Museum. The competition uses a flickr pool to receive submissions, meaning people will be able to see other people's designs before the May 14 deadline, a rarity in the world of art/architecture competitions. Participants are invited to be "truly creative...your dream interventions designed to capture the full potential of the Guggenheim's rotunda...need [not] be limited by any sense of reality."
