Sounds interesting. Are you sure you're not thinking of the effect you
get with 3D displays when there is a discrepancy between the amount of
focusing of the light that your eyes have to do, and the amount your eyes
have to move together in order to both be pointing at the same thing?
These two depth cues always agree with each other with real objects, but
not with all 3D displays. This causes nausea because the cause of this
during human evolution was usually poisoning, and vomiting is a one way to
get rid of poisons -- at least, that's the story.
