Out of all the weird, wacky devices and gizmos that have been releasing lately thanks to Kickstarter -- Android gaming consoles, omnidirectional treadmills, 3D printing pens -- only one really seems to be onto something big: the Oculus Rift. An affordable virtual reality headset, the Rift actually works as promised -- something many other Kickstarter projects fail to do. Now, the headset has received a hardware upgrade, making it an even better device.
