These are stereograms. You can see them in 3D. Look at the picture and then focus through it into the distance. It takes time, but after some time of focussing you should see the 3d image pop into view.

Put your nose right up against the image. The image will become very blurry. The point is you have just easily defeated your tendency to focus right at the surface of the paper. In order to see the 3D image you must look through the image, not at the image.

Ask yourself what your eyes feel like because you need to maintain the same feeling and the same posture of your eyes as you move away from the image. Check yourself again. Your focus is completely relaxed. The image is blurry. You are staring through the image, off into space.

Now slowly take a step back from the paper while maintaining the same position of your eyes. Allow the image to remain blurry. Relax, breathe, blink.

Continue to walk very slowly backwards, away from the paper. The hidden 3D image will gradually come into view.

Continue aiming your eyes beyond the paper. Do not look directly at the image or the paper. If you suddenly shift your focus and look right at the image, you will lose the 3D effect. Try again.

Once you recognize the 3D shape, if you continue to look into the background rather than directly at the shape, the 3D effect will increase. Stereoscopic perception seems to have a saturation effect in the brain, so if you keep looking at the image for a while you will notice that your perception of the depth increases. Cool.
