One example was a “sunlight projector” developed by ARPA for psychological operations teams. As the name implied, it was a movie projector that used a mirror—a shaving mirror in this case—to focus sunlight on movie film to project it on a screen. The idea was that this sort of ruggedized equipment could be easily carried into small villages to play government propaganda films. An American psychological operations team actually tested the device in 1965 in a small village. The results were not good: the projector ended up focusing too much sunlight and burned a hole through the film.
