Point Light Figure Recognition

The above animation (from http://www.pnas.org/content/112/4/E361/suppl/DCSupplemental) uses only nine points to evoke the figure walking.

Johansson’s ground breaking point light experiments have given rise to whole field of research into the perception of bio-dynamics, including this interactive sex-changing walker at BioMotionLabs.

Johansson in his work managed to evoke the movement of a human leg with just three dots.

I want to do something equivalent with a still figure. That is, I would like to explore the minimum marks required to draw a recognisable figure.

Of course, people have been seeing people, animals and objects in dots of light in the sky for thousands of years.
