2.5 d Front Projection Moves to 3D

I am a big fan of the illusion created by 3d projection. That's a technique by which some form of video or film is projected on a non-square surface for the illusion of life or movement of the object. It's a neat effect that I first saw at the Smithsonian Institute. They projected the video of presidents speaking ( Lincoln, Washington) on a smooth generic bust of white marble. It made the bust come alive. Although, they call it 3d projection I want to say it's more like 2.5d than 3d. These projections are often done on a grand scale ... like buildings. Here is one for the promotion of the movie the tourist.






The best of these take into account the structure of the building which really makes the illusion wild. I have recently discovered a 360 degree video projection on a sculpture of a man crouched . The projection happens in real 3d as you can walk around the sculpture and see it transform from all sides. Pretty neat. The company responsible for the 360 projection is Drawlight in Italia. Check them out.
