"The Simon & Garfunkel song “At the Zoo” gave us the visual storyline and structure that enabled our imaginations and graphic abilities to run free. Some footage was shot live-action, 16mm, and then reanimated on an animation stand. We would blow up frames onto large Kodalith sheets, adding gels and make many overlapping passes on the stand. We edited the visuals to the beat of the soundtrack. It was all experimentation, new ground for us." -- Filmmaker Phyllis Chillingworth
