It's funny, because looking at this sort of scene in "standard" stereo
formats doesn't affect me much - whereas the "Gap" dolly motion effect
was quite pronouced for me! Now, that looked *strange*. Which is why
it was used in ads, I suppose. Of course, being "programmed" to see
3D easily, it also was quite a jolt to be watching a "flat" ad, and
suddenly seeing it jump from 2D to 3D, unexpectedly. Almost a Star Wars
"jump to lightspeed" effect in some respects!

It's been quite a few years since I've been in an IMAX theater, but
my first experience with one in Fort Worth had the same lead - except
in this case it was a flyover of Fort Worth. Even though not in
stereo, it came close to making me nauseous, and I'm not normally subject
to that. I suspect it was because of the slight up/down jitter of the camera
attached to the 'copter, or perhaps the stroboscopic effects from the
overhead blades...
