Patterns in life.

I'm trying to find a film about patterns in life. I remember a scene where wheat in a field is swaying & making a pattern the film cuts to a slaughterhouse where Ducks are hanging upside down on a conveyor belt with their heads swaying as they move along. There are lots of natural & man made patterns. I only remember these 2. I don't think there was any talking just music in  this film & I think it was a short film
