The last few years I've been working with a super small team to build an avatar creation platform.
At the beginning the process required a 3d scanning booth with 70 cameras and perfect lighting, but now it only requires a mobile phone camera and two photos.
The avatar created from those 2 photos is production ready for our GIF keyboard. We have prototyped it's use in VR and games as well.
It was available for ios and android but we're making some big changes and it'll be back.
