NAB 2012: NICT 200-inch Autostereoscopic Display

And now for something completely over the top—an autostereoscopic (glasses-free) 16:9 rear-projection display measuring 200 inches diagonally! This behemoth was developed by Japan's National Institute of Information and Communications Technology (NICT) and consists of 200 small DLP projectors behind a special diffuser screen and Fresnel lens. Amazingly, you can walk around and see objects from different angles and even behind them, much like a true hologram.

There was some obvious vertical banding in the 1920x1080 image, but I found no one who could explain why. Perhaps it has something to do with the diffuser screen creating a narrow horizontal diffusion angle and a wide vertical diffusion angle, as depicted below:
