The videoclip below is a demonstration of the prototype of SecondLight, a Surface-like application developed by a team of researchers at Microsoft Research UK. If you place a tracing-paper like object on the surface, secondary information regarding the content on the surface can be revealed. The system relies on a projector system and a special liquid crystal on the display.

Here is another video from Slashgear that describes SecondLight. According to the video, SecondLight is a multi-point display, displaying images on a surface, and images through a surface. The system has two hi-res cameras, two projectors with optical shutters, infrared illumination, and an electrically switchable diffuser.

SecondLight can track images from a distance, track IR reflective objects, and also track IR emissive objects with mobile, multi-point touch detection.
