wtach 3:37 of the johny lee video and youll see how this system contrary to 6dof is like a window since IT CHANGES FOV with position
this other video reflects two things:
1) how the johny lee system is old and widely used in media if you think about it, game design is light years away from tv media
2) for what i know bin laden could not be death, 911 could have been a green screen thing, in fact even nyc could be a green screen thing
