About 3D Stereograms

This group is dedicated for sharing Single Image Stereograms also known as Magic Eye pictures.

Stereogram images create the optical illusion of depth when the viewer allows his or her eyes to focus behind an image (diverge), or focus in front of the image (converge). The slight differences in vertical repetitions of figures, patterns or random dots create the illusion of depth in a 2D image, just as the slight difference in perspective between one's eyes creates the perception of depth with 3D objects and scenes.

Please note that due to flickr's policy stereograms are often marked as NIPSA images and thus are not visible to public. In order to view all of them you need to join the group.

We also have animated Stereograms as well. Because they are in GIF format, please see them in full size for animation, though we'll be adding animated image into stereograms comments.



Stereograms had been in existence for years before being re-popularized by the creation of computer generated random-dot stereograms (SIRDS). Traditionally, you make a stereo image by taking two photographs of an object or scene rom a slightly different angle (see stereoscopy), but in Single Image Stereograms the image is hidden until the viewer focuses their eyes correctly. The Magic Eye series helped bring stereograms back into favor with the general public.
