I have one for you: the vestibular system works in concert with the eyes for "image stabilization" purposes, so when you are eg. walking around, all that up-down head motion is canceled out. Visual vertigo occurs when the two systems fall out of sync for some reason.
The same when you play a videogame with a heavy “view bobbing”. Someone decided that it would be more realistic if your camera shook by 15 degrees both axis at every move (looking at you, cod:mw), but it only makes a scene feel sick and you can’t turn it off.
