I hope it can be disabled. I don't mind it myself, but my wife is one of those people who gets sick (motion sickness?) when watching 3D movies or playing video games, like the OP is describing. It's not an overreaction, guys; some people are just really sensitive to that kind of visual effect. Drives me nuts TBH (my wife hates video games, which means no multiplayer deathmatches, etc) but it's not like she chooses to get physically ill when she sees my iOS7 springboard.
It can be.
