Another is to place two pennies on the table and look at them, letting your eyes go out of focus until you can see three pennies. One way is to stare at something that is about a foot behind the page (or your computer screen) and then quickly look at the pattern without focusing on it. If you have trouble seeing the image, there are several things you can try. Once you can see this one, get out your word processor and try adding and subtracting characters to see how it changes the 3D image. Create your own screensaver from JPEG images, using lots of slide effects and background sounds. Your brain decides that they must be behind an edge, so you see the block of text sticking out towards you. An API that will assist you in creating stereograms. This time there is a difference some of the zeros are missing. When you look past the page, your eyes focus on different parts of the pattern. In the second stereogram, we changed part of the pattern. With the top stereogram, both eyes are seeing different parts of the pattern, but because they are both the same, you still see a flat image. Your brain combines these two different images into one three dimensional image, letting you see depth by comparing the two images. Also, some parts that your left eye could see are hidden. Since it is looking from a different angle, it can see some parts that your left eye could not. Notice that the image you see has changed a bit. Then switch eyes, closing your right eye and opening your left. Look carefully at the edges, noticing which parts you can see. It could be a lamp, a chair, or even your little brother, if you can get him to sit still long enough. To understand that, we need to understand how we see things three dimensionally. When you get your eyes focused properly, you will see a block of numbers raised up in the center of the three lines that we removed the zeros. Now look at the pattern in the same way you look at other stereograms. Both eyes see the same thing, so it just looks flat. You can try this with the pattern above, but it won't do any good.

When you look at the pattern, you want your focus to be behind the page, so that your right eye is seeing the pattern in one place and your left eye is seeing the same pattern in a different place. You will need your computer and a program where you can type.īegin with a repeating pattern. Have you ever wondered how they are made? Lets take a look. Have you ever seen a random dot stereogram? You see them on posters, cards, calendars, etc? It can be a random pattern of dots or a repeated pattern of just about anything, and if you stare at it in just the right way you suddenly see a 3 dimensional image sticking out of the page.
