I'm a swivel-eyed loony
At a very young age I was diagnosed with a "lazy" eye, which wanders off to one side of its own accord. I'm not entirely convinced that's the proper medical term for it, but that's what I was told. Various attempts at curing my lazy eye have been tried, including spectacles, ocular muscle exercises, and more I've long since forgotten. The spectacles help with my myopia, but don't do a blessed thing for my lazy eye. The ocular muscle exercises merely taught me how to cross my eyes, something which I'd previously been unable to do. All too often I'll end up concentrating with one eye while the other one gazes off to the side. Which eye does which varies from time to time.

The upside of all this is that it's very easy for me to see those "magic eye" pictures, the ones which look like so much random noise until you unfocus your gaze slightly. I can also move my eyes independently of each other. I can stare straight ahead with one eye while swiveling the other eye inwards to look at my nose or outwards to stare at my ear. This is, apparently, quite disconcerting to observers, so I've been told.

Autostereograms!
How odd. I was just doing those this morning. I love them! =D

Lazy eye! / Strabismus
I had the same thing, not knowing it could be corrected until recently, (I'm 31), had on operation 2 months ago.
Now my mates call me "Straight-eye" instead of "Cod-eye"
I have never been able to see those magic eye pictures though, and don't get me started on 3D films...
