You know how you just can’t go back to watching normal resolution television now that you’ve gotten used to HD? Well the next era in TV technology is fast approaching. In the same way that HD killed low-res, 3D televisions will eventually make 2D images seem artificial and lifeless, no matter how clear and sharp the picture.
Case in point: 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.
