I'm sure most of you have seen the 3D images, that pop out when you look at them a certain way. That's what my page is about. I've looked on the Internet and found some very interesting and tricky ones for you to figure out. Some people can easily spot them, while others have a much more difficult time. If you can't seem to get the picture you can try these methods that I've read about: Put your face close to the screen so that your nose is almost touching the picture. Very slowly start to pull your face away from the screen. An image should start to appear, but it will probably be blurry. You will lose your focus if you try to actually look at the picture so just keep pulling back slightly. If that fails, try viewing by slightly crossing your eyes. Try to look behind the picture. Try to imagine something behind the picture and the image should appear. If neither of these methods work, you're one of the people who can't see autostereograms. Don't be discouraged ... it's hard to do if you've never done it before. But for those of you who can spot them, enjoy the next few pages! This picture if just for practice. When you first view the picture you see just two dots, right? Put your face about 20 centimetres from the screen and to look between the two dots. You should eventually see the three dots. It might take a while, because you're probably not used to looking for images that are almost "hidden". Keep trying ... you should get it soon enough. When you do, you're ready to move on and look for the images in the next few pictures. See some actual autostereograms ... go to the next page.
