Virtual reality sounds almost quaint in these days of OLEDs and 4K and the Kinect and glasses-free 3-D and all the other amazing ways we have now to experience and interact with games. But it's back in a very, very big way with the Oculus Rift, which I tested out today here at CES in Las Vegas.

Oculus started out as a hobbyist project from one Palmer Luckey--just a guy with an idea, taking apart smartphones and making what turned out to be a predecessor to the Oculus Rift. Luckey posted about his project on a forum, where it was found by gaming legend John Carmack, creator of Doom, Quake, Wolfenstein 3D and more.
