Some old time 3D images

Here are a few classic stereoviews adapted to the new animated "Piku-Piku" format.   All classic 3D images, and indeed most contemporary 3D images, consist of a left-right pair.   For the "Piku-Piku" an additional 10 intermediate images are synthesized between the left and right originals.  This makes it possible to create lenticular prints (like the 3D baseball cards you might have seen) which aren't possible with only two images. The back and forth animation is one way to present a 3D image on a flat computer screen.
