Stereograms are quite amazing pictures for those of us that are able to focus on them correctly to be able to view them. Stereograms are pictures that have a 3D picture hidden within it. The 3D picture is not immediately visible until you re-adjust your focus to a point beyond the initial 2D picture. The idea is, you have to make your vision a little blurry, almost cross eyed. Play with your focus a little and when you notice a hint of something that looks remotely 3D, try adjusting your focus in on that. With a little persistence, you will see a clear 3D image. The effort put into adjusting your focus on these types of pictures is well worth it. Stereograms are truly amazing pictures.
