Super impressive, and I can see it being useful in many cases already. Especially making interactive experiences in combination with position tracker of a user in a room. As you move around the room your perspective changes.<p>In a more creative approach I could imagine creating fake windows using flat-screen TVs in this approach as well. As you move around the room the perspectives would change as well, giving an illusion of the windows being real. Of course this would only work for a single person at a time but it would be quite interesting to experience. It should not be too difficult to hack it together as a solo dev.
