Nice idea. We are planning on running some contest/events for players with various themes and I dont see why winner's work wouldn't be added to cinemas, but I will have to check this out with higher authorities.deiben is probably right, or at least close.
But the contest Lucky mentions could probably be an ongoing thing. Not as a contest but as fan/player submittal. Players would make short Inno game themed clips to be played in the movie theater. Wouldn't cost Inno anything to produce or upload it to the theaters and offer a change of pace for movie goers
