Watch FMovies. This is a film with minimal content. Using a film pen, a line was drawn across a strip of clear leader, until it hit the edge of the frame ("cheers"), and then the line was drawn back to the other side ("cheers"), etc. This strip functioned as the film negative. The projection is the drawn out line as a white line that wanders back and forth, bringing light and darkness into the theater. Because of this one should not only watch the movie screen, but also the light that comes out of the projector and the reflections in the theater. A "light play." (E.S.jr.)
