Kinetic Necktie-Tying Sculpture

Why Knot? - A kinetic sculpture by Seth Goldstein

The YouTube description calls it "A kinetic sculpture that continually ties and unties a necktie."

I am not sure whether this fits best into the category of "art", "satire", or "technology". It is not a modern takeoff on Rube Goldberg, but rather, an experiment in robotics and perhaps topology.
