Goes to show what a small change can translate into. Although not by itself, perhaps there's another way to look at it which is equally cool, because he had to align all the pieces to create the effect, so small choices can translate into larger effects, much larger than the tiny choices, but it does require to keep that larger goal in mind, lined up with today's choices. The tiny piece could not tumble the largest one.. but if it's lined up adequately, and cumulatively, then it certainly does.
