While TV manufacturers are looking into the optimal way to display 3D without the need for glasses, the apex of this technology in the last century, was stereograms. The public library of New York has an extensive archive of such photos, which they decided to use in a simple but smart way. Each pair of photos is unified in an animated GIF, so that users can watch a short looping animation, which gives them the illusion of depth. This is made possible by the Stereogranimator project, which obviously, for some reason, could not have had an easier name. The library’s collection includes more than 40.000 pairs of stereoscopic photographs, which can be converted into animations. Visit the above mentioned website to watch the already converted images or choose the ones you want to convert.
