This is a cute action model, counter-balanced so it actually rocks back and forth:

It is supposed to be 2 children, opposite ends of a see-saw – a boy (wearing an Indian costume and feather) and a girl (in a bonnet) – use your imagination or some recreational chemicals and it is as clear as anything.

Designed by Fred Rohm, I folded this from “Secrets of Origami” by Robert Harbin, one of my oldest books – a simple model as I was brain-fried after a punishing term, hope you like it.
