I came across this cool little table a few days ago:
I don't know whether it would actually help with privacy or concentration, but it would definitely make for a very stylish office. Although, my first thought on seeing the screens is that it could easily be used as a theater as well. I mean, if the screens change anyway, I'm guess you can put anything you want on them. With the screens spread out into a hemisphere, you would have your own IMAX Dome theater. Which would be absolutely awesome.
Wouldn't be quite so awesome if your boss caught you with that. I wonder if you can get the image on the outside to be different from the image on the inside?
