I thought this was an amazing video demonstration of 3D Projection Mapping being used as a backdrop during a live show presentation.

This process works by projecting imagery onto a multidimensional light colored plane.  The light colored plane is first replicated in 3D software to match its contours.

Here is a another cool example of this technology produced by www.easyweb.fr .

This is the wikipedia explanation to this process : http://en.wikipedia.org/wiki/3D_projection
