Of all of the experiments we did in our film school animation class in 2004, drawing on film was by far the most tedious to me. If you keep in mind that 24 frames equal one second of screen time, it meant having to replicate an image over and over again to create the project - or at least it should have.
I chose instead to go the completely experimental (and in many ways easier) route, and opted to create a colourful film strip inspired by frequency lines. I divided my film strip evenly between frames of green, red, and blue. This was done with a clear strip of 16mm film and pack of sharpie markers. On top of that I drew various lines that would fluxuate in contrast to one another. The result was as busy as you might expect, but it created a cool effect. See what resulted below.
