This effect goes back way before FPS video games.<p>Eg, I got this badly as a kid in the early 80&#x27;s at Disney World, in the O Canada! Circle-Vision 360° theatre. Within seconds of starting the movie, I felt the whole room moving around and I nearly hurled. Luckily since the room is stationary I just sat down with my eyes closed for the rest of the film and recovered pretty quickly afterwards.
