Know what's really hard? Grab a flashing/blinking bouncy ball, and try to play catch with it (or juggle) in the dark.
This is particularly striking since batting involves judging the ball that comes at you with some speed. His previous judgement and muscle memory might be useful of course. But I'd love to read about any research on this, if anyone is aware...
Unfortunately, despite this, they weren't willing to let him go back to flying fighter planes, which is why he got into space suit research...
They do it by moving their head - watch for a while, they almost always run a little bit along the branch before jumping. Sort of like synthetic aperture radar.
Apparently there was an artist who wore an eyepatch for a few months, after which his brain stopped the 3d effect, and he essentially was seeing in 2d.
This of course was all stuff told to me in an art class on perspective, so take with a grain of salt.
Don't take my word for it, close one eye and move your head from side to side and see the 3d jump out at you.
Speaking as someone who naturally has little to no depth perception (amblyopia affecting my right eye), I still see 3D just fine, catch flying objects (balls, frisbees, etc.) just fine, and am not disabled in any significant way except an inability to see into those magic eye puzzles.
Two eyes give you the ability to detect parallax without moving your head; those of us without binocular vision detect parallax by slight (imperceptible) movements of our head. There are many other useful visual artifacts of our 3D world: closer things are larger than farther things, closer things obscure farther things, and so on. Our brains just construct 3D worlds based on those data rather than the simpler, more reliable stationary parallax detection that you two-eyed folks use.
But the difference between what each eye sees is also an important factor in 3D vision. Movies just make it the only factor, which is probably why they can be disorienting. My guess would be that it's more important for things that are close than things that are far away; something 3 inches from your face appears to be in drastically different positions if you cover alternate eyes, but distant mountains look about the same.

I will kick your ass at pingpong. Science, Fuck Yeah!
Dear Sir,
Your submission that an eye patch would cause the wearer to see in only 2 dimensions is false. I myself wear such an eye patch full time (here is a self portrait for illustration: http://www.petermichaud.com/about/ ).
I have not seen from 2 eyes since I was 7 years old, and I am perfectly capable of seeing in 3 dimensions. To prove my claim, I can also perform tasks traditionally associated exclusively with 3 dimensional vision; for example, I excel at ping pong.
For a tldr; see my much shorter and more entertaining parent comment, which was downvoted into oblivion.
Thank you.
1. Obtain one pair of glasses
2. Pry apart at the seam with a putty knife or small flathead
3. Remove one of the gel lenses
4. Flip it over and put it back in, note the areas that need to be trimmed
5. Trim with scissors
6. Reinsert gel, stick the plastic back together
(Edit: come to think of it, there may be some trimming needed if the left and right glasses aren't the same shape but in that case flipping them over would probably work unless they are curved)

Note that if the slit is narrow enough, it will still focus light thought the pinhole effect (also giving you polarized light (if the material is electrically conductive)).
Anyone know how IMAX is different?
Come to think of it, normal polarized sunglasses should work as linear polarization filters assuming they line up the right way.
I've actually marked the edge of the circular polariser filter I have for my camera so I can tilt my head (wearing polarised glasses) and then quickly move the filter to match.
In this Ohio theater they used a belt and suspenders approach where both polarization and timing were used to create the 3D effect. Left and right eye frames were projected through polarized filters and the projector itself was constructed so that one of the shutters would always be closed while the other was being displayed. The headsets handed out to the audience were active; they had LCD lenses and an IR receiver which would align the timing to the projector's.
This was purportedly done to increase decrease the "crosstalk" between the two eye views and worked quite well.
* Edited to reflect Cushman's observation on circular vs linear polarization.
I assumed they were serious. Plenty of people are dragged to 3D stuff even though it bothers them.

This could really help fight the rising incidence of 3-D media watching associated dysphoria.
