The Digital Wallpaper by strukt studio.
"The basic idea was to light up the black and white striped office wall by mapping the architecture with multitple projectors. The program developed by Strukt is scripted in vvvv and is scaleable to any number of projectors and any architectural shape. Several different visualisations have been realised already, amongst it a Pac Man animation as well as moving stripes, and more are in development. The content could also be made interactive, reacting to people passing the ground-floor offices."
