The entire video was hand-sketched frame by frame using the iPad. Each time Harris removed his finger from the canvas after a brush stroke, the Brushes app would record a frame. Thirty brush strokes created one second of animation and 7000 created the entire music video. The resulting frames were exported from the app and compiled into a single animation.
Every movement in the animation is perfectly choreographed to the band’s debut single Undivided which features Snoop Dog. Not only is the animation lively and entertaining, the music is pretty good, too. You can check out the music video above and Harris’ explanation of how he made the video below. [Mashable]
