A ton of 360-degree photos and videos are uploaded to Facebook every day. The challenge, if you own a Gear VR headset, is finding the best stuff in the Oculus Video store, or amongst the deluge of selfies and viral videos that make up most News Feeds. To help, the social network has built a new app for Gear VR called Facebook 360. It's a basic interface with four tabs that help you browse and launch 360-degree media. "Explore," for instance, lists the most popular uploads, while "Following" collects everything posted by your friends, and the pages and people you follow.
