    That second video reminds me of… electric football. Before the days of video games, we had electric football, a sheet of steel painted to look like a football field, mounted on a short box-like stand. A vibrator underneath would loudly vibrate the sheet steel, causing plastic football players on brush-like bases to scatter around randomly on the playing field. Before each play, you’d set up the players as you wanted, put a football (felt or foam rubber, I believe) in the arms of the QB, flick on the power, and watch them run around aimlessly until the QB fell down.

    Great fun for about three minutes at a time until you realized skill wasn’t involved.

    Interesting connection you point out – Some philosophize that we too are driven by vibrations (like the hockey figures). I don’t have a citation handy, but the study of cymatics goes pretty deep.
