In Pictures: Android 4.2 - A visual guide to what'...
One of the most interesting new elements in Android 4.2 is something Google calls Photo Sphere, which builds upon the panoramic photo function introduced with Android 4.0 and turns things up to 360 degrees -- literally.
Photo Sphere uses the same technology as Google Street View to let you capture interactive 360-degree images and share them with friends. Just follow the system's prompts to snap images around you and then watch as it melds the photos together into one giant sphere.
Due to their interactive nature, Photo Spheres can be viewed only within Google Street View or Google+ (or on an Android device). Check out some of Google's sample Photo Spheres to get a better idea of what it's all about.
