(animated stereo) Holtz machine emitting sparks, 1876

The purpose here is not to duplicate the original image, from Libraryimage.net's stream, but to generate an animated gif to assist viewing. Unfortunately, animation is not automatic - to animate you must view the image at original resolution (click all sizes) or simply scroll down.
Libraryimages,net posted a vast archive of photos (panoramas, stereoviews, 19th century, etc.) with much CC licensed. The original image (circa 1876), presented for parallel viewing and showing a Holtz machine emitting sparks is one of many fascinating 19th century stereo compositions. This animated gif version exploits motion parallax to give a stereo illusion without eyestrain, to see what the photographer envisioned.
