I played with metronomes all the time growing up. But, I never experimented with them enough to create a hypnotic video like the one below.
Radiolab.org has posted two videos about metronome synchronization. “As the metronomes tick back and forth, they affect the table, and because the table is designed to absorb the motion of the metronomes, the table itself starts to move. Now that the table is rocking ever so slightly, it begins to affect the metronomes on top. Metronomes that are moving with the table keep doing that. Metronomes not in sync with the table have their motions dampened, then countered, until they do it “the table’s way.” Eventually all the metronomes come into alignment.” (via Radiolab.org)
