For me, I want a historical movie theater kind of experience. You can go to any place at any time and place yourself in the environment and observe how things happened in that moment.

For example, I'd LOVE to be in the Oval Office the day that Kennedy's generals presented him with the news that Soviet Missiles had been located in Cuba. You would be in the room, could see and hear everything going on, but no one could see you, hear you, or anything like that. You can pause the event, fast-forward, whatever you could do with a movie.
