The difference between Kinoautomat and Eno is that Eno actually doesn't give the user more freedom, since the scenes are randomly selected rather than selected by the audience. To put it another way: if you watch Kinoautomat twice, you can technically have the same experience twice.

Clue did something like this in 1985. It has a few different endings which were shown randomly in theaters, no indication of it either. It didn't go over well though.
