U2’s 360° Tour set was designed so big as to be invisible. It’s not invisible (people have been calling it “the claw”), but it is constructed cleverly to allow for more seating and new attendance records. The L.A. Times has several interactive graphics that demonstrate the stage’s conception and construction. Three skeletons of the set were created to allow U2 to play in one city while set up begins in the next. 95,000 people were expected at the Rose Bowl in Pasadena, CA last night (the show was streamed on YouTube).
