FRAME
FRAME is a platform where you can create immersive spaces (called frames) in which you can work and play.
FRAME works across a number several types of devices, including VR headsets. At the time of writing, it is still in beta, but even at this early state it is polished and well designed. People are using frame to collaborate on work projects, host events, and spend time with their friends.
I hope to see many public Frames in the Extended Collection in the future.
