• In 1861, a U.S. patent was issued for the kinematoscope - a photographic attempt to show motion - to Coleman Sellers as an "improvement in exhibiting stereoscopic pictures of moving objects". A series of still pictures with successive stages of action was mounted on blades of a paddle and viewed through slits passed under the lens of a stereoscope revolved at right angles.
