You know movies and futurists have for years been promising true "virtual reality"? Well, the Oculus Rift Gaming Headset ($300) can get you tantalizingly close. Currently available for order in developer kit form, the Rift utilizes dual 1280x800 monitors sitting just inches from your eyes to create a realistic, 3D VR gaming experience. Want to look around in the game? Just move your head. It's as close as you're going to get to having a personal holodeck for the foreseeable future.
