Cardboard pairs with your handset via NFC, and there's already a handful of demos for the app. How the project works with Google Earth, YouTube and Photo Sphere seems pretty self explanatory (the standard experiences for those, but on your face), but Exhibit, Street Vue and Windy Day are a little more intriguing. Exhibit allows you to gawk at cultural artifacts from every angle, according to its description, while Street Vue consists of a drive through Paris and Windy Day is an interactive animated short.

Sure, this seems like little more than a novelty compared to the likes of the Oculus Rift, but even with that influx of cash from Facebook, Oculus still needs to charge for each headset. With Cardboard, Google has probably undercut everyone in the field on one of the most important aspects: price.
