The praxinoscope is an optical or moving image toy. Was patented by the French É. Reynaud in 1877. The improvement of his camera on the Zoetrope in image quality resulted in immediate popularity. This science toy with animated images uses the phenomenon of image retention to make us believe that we are seeing moving images. As you turn the drum you see the reflection of the images on the mirrors, which give the impression of moving: a perfect animation. With 19 animated bands to play. New bands could be made on request.
