This is just awesome, it's even better than the ones in the magic-eye books, those were kinda blurry most of the time. But this is perfectly sharp, I can see each and every turret, and even look around. Kudos to Galemp

EDIT: Moving your mouse cursor over it while looking at it in "3d-mode" is _really_ weird.
For those who don't see it: It's easier to let it "snap" in, when you know what you're supposed to see. So, you should see an Orion in roughly isometric view, with the engine section on the left edge and the bow coming at you in the centre of the image.
The plane to focus on is about 0.5-1m behind your monitor (if your sitting about 30-50 cm in front of it), so when the 3d effect snaps in, it's like there's a "room" cut out behind your monitor with the Orion floating in it.
Just relax your eyes and let your mind wander (thus not focussing on your monitor)....if the image starts to form, don't move your head and try to ignore that you're looking at a flat monitor.
Once the effect snaps in, you can focus on the Orion and the plane behind it without loosing the effect. And if you've done it once, it's very easy to look away and the look and get the 3d effect very quickly.
