If you haven't seen the video of the card stunt pulled off Saturday by the 70,585 fans at Iowa's Kinnick Stadium, here it is. The stunt was executed before kickoff against Northwestern.
Having attended an Iowa game or two back in the day, the amazing part had to be that officials were somehow able to get fans to leave the tailgate early. Frankly, it takes a lot to separate Hawkeye fans from beer.
After the jump is a time-lapse video of the game shot from the north end zone by Cedar Rapids Gazette photojournalist Brian Ray. The card stunt appears at the 40-second mark.
Ray shot the video with a Canon 5D Mark II and wide-angle lens. Images were shot every four seconds, and nearly 5,000 were captured. Ray explained how the images were stitched together in a video on this page. The card stunt cost the university $80,000.
