The new Walker: Described as a "giant ice cube" by Newsweek, the new Walker Art Center in Minneapolis opens this weekend. Designed by Pritzker Prize-winners Herzog & de Meuron and clad in reflective expanded-aluminum panels, the building doubles the size of the Walker, throwing in odd touches: a talking dolphin, a tabletop computer equipped with gesture-recognition apparatus, a "theater tower" that's cantilevered 50 feet over Hennepin Avenue, a new Skyspace by James Turrell, and more. It's also where I work—and the reason I won't be blogging much this week.
