Take Microsoft Surface, sprinkle it with fairy dust, and you might have something close to Microsoft's SecondLight, a new technology in the works from Microsoft Research.
The experimental SecondLight technology adds a second dimension to Surface, allowing users to slide "magic lenses" over the display to provide a second surface that can be linked to the first. In one example, Microsoft researchers projected a picture of a car on the Surface display. But add separate, portable pieces of glass that can be moved across the display, and presto! the glasses are transformed into "X-ray specs" allowing a wireframe model to be viewed.
It's all sleight of hand, of course. But if history is any guide, SecondLight will eventually be part of future Surface displays.
Thought this was cool. More at the link above.
