kkleiner writes "Japan has unveiled a new 200-inch, HD screen on which images shift through 57 different viewing angles to give the appearance of 3D – without the need for glasses. The trick behind the glasses-free 3D is an array of 57 projectors behind the screen, each projecting the same image at a slightly different angle. As awesome as the images are, the screen is not quite practical. You’ll need an extra room for the array and a forklift to move its 500 kg."
