Google Cardboard VR Headset
Let's face it: as cool as the Oculus Rift is, its limited utility makes it a tough sell for the price. But what if there was a way to make a VR headset for just a few dollars? Well, that's exactly the idea behind the Google Cardboard VR Headset. Using nothing but cardboard, a couple of lenses, a couple magnets, velcro, a rubber band, an app, and some very simple instructions, you can transform your Android handset into a full-on VR viewer, provided you don't mind having a piece of cardboard hanging off your head as you "ooh" and "aah" your way through the available demos.
