Google Developers Blog: Google Cardboard: Seriously Fun. Okay, I get it. Nobody wants to spend several hundred dollars on me for Christmas. So, no Virtual Reality headset for me this year. However, there is a frugal alternative, and it involves a cheap cardboard kit that can accomodate the Galaxy Note 4. Slide the phone in, and, presto, you have a VR viewer that will render compatible apps and video in 3D. So, strap on your bluetooth headset, load up some 3D video, and rock on.
