Okay so this video is kind of hard to explain, but basically he even states in the beginning that it took 238 takes to get this right.  He has four iPhones set up, all using different videos, and he and another person piece them together as the videos move, it's kind of like a constantly moving puzzle, oh and he plays Fun's 'We Are Young' on a guitar.   Now that I'm sure you're confused as all get out, check out the video below and see for yourself how incredibly awesome this is.
