That reminds me of the days when college kids would set up about nine thousand dominoes and then tip the first one and the wave would run along, up a set of stairs, down a set of stairs, around in a circle, and on and on. My son and I used to play around with dominoes and we only had a few hundred. It was still a study in frustration when we were almost finished and accidentally knocked one over and all your work was gone in a few seconds.....Oh to be young again...
