Great creative work from Saatchi & Saatchi LA for the Toyota Prius. Using the new Prius iPhone App, users could see their drawings created on the iPhone displayed on the Reuters digital billboard in Times Square from October 26 to 28. The Prius Experience App has four modes — including "Draw," the one showcased in the above clip.
