I saw some "cross eyed 3D" pictures that were pretty impressive so I thought I'd try one my self. This is my first and only attempt. Once you "see" the 3D effect, it's very realistic. To view them you basically just need to cross your eyes: Focus on the grey line, then cross your yes. What you'll end up seeing is three images. Once you cross your eyes to get the three images, carefully focus on the middle image, it will be a 3D image of the two on your periphery. It can be difficult at first, but after "getting it" the first time, it comes more easily. If you're not quite sure how to view them, a quick google of "cross eyed 3D" turns up plenty of examples and viewing tips. The pictures are really rather easy to create too.
