First there was the silent classic Man With a Movie Camera. Then Jamie Stuart made Idiot with a Tripod, a video about the great New York blizzard that went viral. Then Kevin B. Lee and Steven Boone created the video essay about the "City Symphony" Films. It was only a matter of time until someone made "Idiot With an iPhone." The approach remains the same: Carefully composed shots build up to a mosaic of moments from life, accompanied by music.
