Many artists envision future worlds, but few actually inhabit them. Not so Mattingly, a sculptor and photographer. Unsettled by predictions of rising sea levels and a post-apocalyptic future à la Waterworld, she dreamed up the Waterpod, a sustainable barge with gardens, greywater system, alternative power and chickens. Mattingly and crewmembers lived on board last summer, docking around New York to showcase their new eco-habitat.
