Google/Daydream Labs released a demo of its Headset Removal Technology that first scans and constructs a 3D model of a user's face and then replaces the VR headset with the face(with real time eye movements, of course) in a green screen recording of the user. Puts the Tilt Brush artist's face back into their creation as they create it, instead of having their face covered by the headset.

The video is by the The Try Guys from Buzzfeed. The interesting stuff starts around 4:43.
