The pattern of the dots' movements is equal to the lights placed at strategic locations on a walking human being. The point I got from it was the pattern of a walking human being (and four legged animal also) was so familiar to us (maybe even hard-wired) into our brains that we can recognize the image with a minimal amount of visual information.
Funny you said that, I just saw a show on Discovery or somewhere where they found dolphins could interpret commands by minimal clues. They put white balls on the hands of a trainer and filmed them all blacked out against a black background so all you saw was two white balls on a black screen and the balls moved in the hand command sequences. They said this was proof of the great intelligence of the dolphins, as they interpret by these minimalistic visual clues- just as we do.
Since I'm posting such off the wall stuff... I also remember seeing how they computer model super-realistic movements (as in the Jurassic Park movie) by using the same balls at body joints against a blank background as the framework model.
Oh, and thanks for the web site link. I gotta go check that out.
