Stuff like this can obviously be used to make things like deepfakes 'better'. But i think it might be cool for creating virtual meeting rooms, where you can take a webcam shot of a persons face, normalize the skin tones for lighting, map to a 3d surface, then relight it for the virtual room.<p>When you can rig the meshes to drive each other you could wear 'masks' of other peoples faces (or critters).
