Recently we mounted the Ficiton Facades installation; it won second place at the Illuminate Yaletown lighting festival in Vancouver, Canada. It consists of a facade projection set up, and writing processing scripts to generate animations that react to building features and generate sound. When the projection is set up and the installation is ‘launched’ a coordinate map that corresponds to the windows is made. As soon as the window map is saved, animated objects appear and move on random trajectories bouncing off the buildings features. The association of sound and visual animation create the impression that the animation is making music off features of the building.
