You can’t move at the moment without someone trying to slap a virtual reality headset on you. Facebook’s Mark Zuckerberg wants us all to put 360° VR selfies on the social network, and Samsung is now giving its Gear headset away for free with its latest Galaxy smartphones. All we’ve had from Apple so far is Tim Cook’s recent comment that VR is “really cool”. We know Apple has hired several engineers and even bought companies with VR experience. But, as always, the company prefers to maintain complete secrecy until it’s got a product that’s actually ready to ship. In the meantime, there’s always Google Cardboard. This cheap and cheerful kit lets you make a cardboard headset that uses your smartphone as a screen for VR apps. Originally developed for Android phones, there’s now a Cardboard app for iOS, and some interesting Cardboard-compatible apps from companies such as the New York Times, and Otherworld Interactive’s creepy horror game, Sisters.
