The OKO camera projector was invented by Kasimir Proszynski in 1912 and first demonstrated in 1914. His unusual design used a strip of film 12cm wide which was perforated on both edges. The camera exposed horizontal rows of 15 pictures 7 x 5mm in size, across the film, which then moved on a step, taking a futher row of pictures back in the other direction. For projection, the same mechansim with the addition of a special electric lamp was used. OKO is Polish for eye.
