‘Project Smith’ 3D eye-tracking phone with motion-sensing UI a la Kinect.

  The screen itself is not 3D, but the front of the phone has 4 cameras
  placed on each corner of the phone, this is to track the user's
  eyes/head and move the UI to give the impression of 3D. Similar to
  what iOS 7 is achieving simply by using the phone's accelerometer.
  The advantage being that it's not based on how the phone moves, but
  how the head moves.
