Norman Mclaren- Creating the Sound

1951. This clip which I found shows how Mclaren created his sound directly onto film.
I found it really interesting to watch as I found out a lot about his work, of which I didn’t know he actually created his sounds by drawing onto rolls of film.
The way in which a simple arrangement of marks created the sound we hear in his short films astounded me into how he done it and made me want to have a go to see what I could create using an old style film machine to translate the marks into sounds.
