Using an app on her phone, Natalie Sigmon created a mesmerizing timelapse of the moments before, during and after the Super Bowl halftime show. The silent video, which condenses more than 20 minutes of footage into 153 seconds, begins with the players exiting the field. It then speeds through the roughly eight-minute stage setup before rushing through Katy Perry’s colorful 13-minute performance with Lenny Kravitz and Missy Elliott. The clip ends with a rapid teardown of the stage. Sigmon, a Chicago resident and remote broadcast engineering coordinator for ESPN Radio, posted the stunning video to Facebook on Monday night.
