The praxinoscope used mirrors instead of slots

Emile Reynaud put a ring of mirrors in a spinning drum so pictures never flickered Patented in 1877, the praxinoscope placed a ring of angled mirrors at the centre of a drum, facing the images on the inner wall. As the drum turned, each mirror showed the next drawing in place, so the eye saw a steady sequence rather than a blur. It improved on the zoetrope's slotted viewing. It sits in Mondo's movies & tv collection, one of 200 facts that each trace back to the reference below.
