Apple patents "I look back at you!" LCD
One for the "the scary future is near" department comes surprisingly from Apple. While I love the general innovation Apple puts into its product its never THAT far ahead of the loop with its products that I would file them under "future fantasie". Not so if the newest patent application makes it into an actual product. The patent talks about a screen that can also look back at you just like you see in the cheesy Starfire movie from Sun and with that Orwell touch to it that your computer looks you straight in the eyes while you are working.
The concept is easy. Put a sensor between every pixel on the LCD panel the sensor then records while the pixel displays.

The question of why is easy answered. The number one problem of webcams and webchats is that you can not look your oponent in the eye while you are talking. You either see him/her on the screen and he sees you looking down or you donīt see him/her at all while looking in the camera and he/she sees you looking at him/her. The "integrated" display would solve that problem. At the same time it could act as (fingerprint)scanner.
Now how you would focus such a beast is not clear (nanomicrolenses only on top of the sensors?). Also have a blanket ready to cover your screen while not using - just in case its watching.
