Not only that the same effect can be achieved with one computer, one
monitor, and a $100 head tracking device.

I take it you've tried one of those things, Chris? How 'bout a PIREP?
I've looked at them, and been intrigued...

For those who don't know what we're talking about, Chris is referring
to a motion-sensing device that clips to the brim of your hat. When
flying a flight sim, this device makes the screen move accordingly
whenever you turn your head, up, down, forward, or back.
(Eliminating the need to use the thumb cap to change views when you
want to "look" out the side window on downwind, for example.)

What I don't undertand it how you can turn your head left, let's say,
without losing sight of the screen, which is still in front of you?
They must somehow make the screen movements disproportionately larger,
to prevent this problem, right? But then I would think that it would
be very disconcerting, moving a little yet moving a LOT? Or do you
get used to it?
