A Peek at SecondLight »
So, take Surface, but the top is an LCD which can flip from opaque to transparent at n fps. Then float some other materials on top of it, and a projector under it that refreshes at n*2 fps. Half the frames go to the lower LCD, half go to the others. Add an object tracking vision system and you can do some really cool things.
I totally stole that idea to make Xray, which works almost as well with stuff you commonly have around the office (assuming you have a Surface unit and three iPhones around the office). The Xray video has been pretty popular, with 52k views so far. Perhaps we’ll get to make something a little more real with it.
