Facebook Spaces lets you and up to three friends hang out in a virtual room where you can chat, draw, watch 360 videos, make Messenger video calls, and take VR selfies — all while appearing as a cartoony avatar based on your recently tagged photos. For now it’s only available on the Oculus Rift VR headset and Oculus Touch controllers, but eventually it will expand to other tethered VR devices.

Why: This is the social VR vision that prompted Facebook to acquire Oculus three years ago. Facebook doesn’t want someone else to be “the Facebook of VR”. It wants to own that market itself, and soak up the long engagement time people might spend hanging out with friends and family scattered around the world.
