We used Touch Projector to paint on a multimedia facade (here: Ars Electronica Center, Linz, Austria). Users simply aim their device at the facade causing the viewfinder to show the facade locally. In this local image, users can now draw with the selected color. The building then changes its color accordingly as if users directly painted on it.
