That's not it. It's not Apple. But it's beautiful and I want it.

This doesn't work the same way as our touch streams.
Here's Jeff Han's web site. http://mrl.nyu.edu/~jhan/
and here's how it works... http://mrl.nyu.edu/~jhan/ftirsense/index.html

I think the screen is backlit with a projector and is not an LCD. The side LED must be a different color of light (IR probably, most likely pulsed) and the backscatter is measured with a camera located back where the projector is. Which means it really IS scalable to very large installations... just pull the projector and camera back and use a bigger screen.
