Cardboard is a little freebie Google handed out at its developer conference. With a handful of demo apps it gives you a fairly basic virtual reality experience — basic, but supposedly mind-blowing. Supposedly. I saw people’s reactions on various forums, and the crowd was unanimous: it blew their faces off, it was the shit, it was unbelievably awesome. So of course I got curious… no, really, curious. So I picked one up. Mine was 20 yuan on Taobao. You can also download the PDF template and DIY one out of cardboard yourself — the box is cheap, the convex lenses are the annoying part to find. When it arrived, the knockoff level turned out to be pretty high. Apart from the missing NFC, everything it should have is there.
