Designer and commercial architecture photographer George Moua has designed and 3D printed a highly unusual photo tool that he calls a stereoscopic "wiggle lens." In short, it allows you to combine multiple frames shot with a single lens into a moving image that appears to have depth.
The New York Public Library has a massive collection of over 40,000 vintage stereographs (two photos taken from slightly different points of view). To properly share them with the world in 3D, the library has launched a new tool called the Stereogranimator. It lets you convert an old stereograph into either an animated 3D GIF (which uses "wiggle stereoscopy") or an anaglyph (the kind that requires special glasses).
Super nerd Doctor Popular recently did a wiggle stereoscopy experiment using two Flip video cameras and $10 in nuts and bolts, filming himself doing yo-yo tricks at AT&T Park in San Francisco. Wiggle stereoscopy is when images from two slightly offset points of view are quickly alternated, resulting in a 3D effect that does not require special glasses to view. A few months ago we shared the world's first music video that utilized the technique.
