If you haven't been able to grab a free Google Cardboard VR headset from various trade shows, under-supplied OnePlus promotions, Conan O'Brien, or anyone else, there's one more option. FreeVRGoggles.com does what it says on the box, so to speak: if you're a United States resident over the age of 18, just enter an address and an email and they'll send you a free Google Cardboard unit. (You can probably use a fake email address... and you might want to.) Slip your phone inside and you get access to all the compatible apps on the Play Store. Why? That's an interesting question.

FreeVRGoggles.com is sponsored by BaDoinkVR.com, and the hyperlink on that last address is tastefully omitted because it is gloriously Not Safe For Work. BaDoinkVR is an adult site that specializes in virtual reality pornography. Their intentions are clear: the site runners want more people to have easy access to the latest wave of virtual reality hardware, and there's no easier way of doing that than by sending out copies of Google's incredibly cheap headset design. If you're worried about an "indecent" VR headset, don't be - the set is branded with a "FreeVRGoggles.com" logo, but is otherwise unadorned. You might say the intended content comes with its own brown paper envelope.

The Google Cardboard design shown off at the site seems to be the original version, not the updated design compatible with larger phones. According to the FAQ, FreeVRGoggles.com's set can be used with screens of up to 5.7 inches. Anything bigger and you'll need special equipment. Now excuse me while I wait for a flood of suggestive comments on this article.
