On the left an electric motor drives a worm gear at 212 revolutions a minute. A sequence of twelve 50-to-1 gear reductions slows the rotation so far that the last gear, on the right, is set in concrete. It would take over two trillion years for that gear to rotate.
The story goes on to link to several other videos of his works. And videos are what are required, because all of his works are dynamic machines, built to convey some abstract concept, or simply to tweak you on the nose; not literally, but I wouldn't put that past him.
