Even if you don't follow football, you'll want to tune into Super Bowl XLII this Sunday. The New York Giants will play the New England Patriots in a stadium like none other in the world.

With an innovative facade designed by architect Peter Eisenman, the University of Phoenix Stadium has a fabric roof and a 94,000-square-foot playing field that rolls in and out at whim. And the stadium's odd shape? Modeled after a barrel cactus, he says.
