Want to enjoy all the 3D goodness you get a home or in the theater when you’re on the go? This device couples with an iPhone to create three-dimensional viewing experiences. The iPhone Virtual Reality Viewer uses free downloadable apps that take advantage of an iPhone’s accelerometer, so that the 3D environments move when the device is moved. Basically, you attach this to your phone and use it like you would use a pair of binoculars. From there users can view 3D movie trailers, play interactive games or go on virtual tours. Of course, if you just move your eyes away for the phone, you can view the whole world in 3D.
