Trust us. This is probably the best BMW Ad you have ever seen. Recently launched in Singapore, right on the walls of Suntec City's Towers 2 and 3. Interactive 3D projection beams high resolution presentation to an intended surface, say a wall of a building and seemingly "interacts" with its surrounding nooks and crannies.

While it doesn't actually detect the surface, the creative people at http://www.zenithoptimedia.com.sg, commissioned to execute the viral campaign manages to serve an almost unreal visual spectacle to any on-looker anywhere within viewing distance!
Watch it!
