This is the Life Wall by Panasonic. An extremely thin 150′ TV that does amazing things. It has face recognition so that it recognizes the face(s) that watch it and adjusts the display or program to that person’s preferences automatically.
How about having a TV that will move with you as you walk around the living room to keep the display right in front of you? The display would be large or small depending on how far away from the screen you were. It could display a screen saver instead of a black screen when turned off.
Powerful life-size images could dance with you, and videophone linkups would look like the caller was in the same room.
