Before there were movies, there were mutoscopes. I remember making flip books as a kid, but they weren't this good. The mutoscopes in penny arcades around the turn of the last century qualified as "peep shows", but damn it all, I haven't been able to find one that is even remotely pornographic.
I did find a link for a Victorian magazine called The Pearl, and though it is indeed sexually explicit, it's boring. The sexual encounters are all the same, the writing atrocious. The plump young maidens are all interchangeable, and no actual "lovemaking" takes place. Too bad.
I love the idea of watching a movie by turning a crank. Love the flipping images that give a jerky, eerie sense of real movement. I'm not sure how they took all these photos, didn't think they had the technology to "film" something like that. But obviously, someone was on to the basic principle of rapidly-moving still pictures creating the illusion of movement. A principle that remains to this day.
OK, here's the link to all the issues of The Pearl, but I warn you it's BORING.
