Blake Shaw & Bruno Levy of art duo Sweatshoppe appear to be painting video on to walls with paint rollers in this demonstration of their video painting technology. An electronic paint roller works in concert with a video projector to create the effect. The custom software tracks the rollers and the video is projected onto whatever surface they decide to “paint” while people in the street point and stare in amazement. The video was shot during Sweatshoppe’s 2010 video painting tour of Europe.
