This past November, all subscribers to The New York Times received a Google Cardboard Virtual Reality Viewer in the mail. Puzzled looks quickly turned to awe as recipients took 3-D virtual reality tours of a variety of locations through the viewers and their cell phones. You simply put the viewer to your face like goggles and play 3-D recorded videos of places from YouTube or the free NYT VR app (available from both Google Play and the App Store). The viewers put you in the middle of a scene, such as New York City or a traditional German Christmas market. By turning your head you could look around the scene as if you were actually there. The goggles can be ordered online for about $4 each from eBay or www.newegg.com.
