Been holding out hope for a real-life holodeck? Well, looks like Japan's got wall number one out of four already covered. We kid, we kid. That Trekkie tech future's still a ways off, but recent prototypes like this 200-inch auto-stereoscopic 3D screen are bringing that illusive reality one step closer to our living rooms. Exhibited during CEATEC 2011, this 1920 x 1080 full HD display plays images at 60fps using an array of 57 projectors, and offers up viewing angles of 13 degrees. What does all of that mean for you? Well, the setup gives viewers a limited ability to peer around projected objects, so long as they stay within a 1.3m (about 4ft) area. It's yet another fruit of the collaboration between the National Institute of Information and Communications Technology and JVC Kenwood, except this one's headed for the realm of outdoor digital advertising. Home theater aficionados looking for a virtual entertainment solution can always opt for Sony's HMD, but that kind of defeats the glasses-free allure.
