Even though this is purely to fuel VR content creation for Oculus, at least the invention is in the public domain (pending OS license and patent grant)
Agreed. Really looking forward to the stiching code being made available on GitHub. I wish that Google would at least release some kind of an API for their Cardboard Camera (e.g. allowing you to pass in a bunch of photos and get a stitched 360 out), but if Facebook makes good on this, it could be even better.
