If you are lucky, and if you happen to be on the Dutch shore of the North Sea, and if it is a windy day (a not-unusual occurrence), you just might see a new sort of creature walking down the beach. This creature will be walking in fits and starts, activated by gusts of wind, animated in one part of its “body” and then another. Atop the creature, you will see sheets of fabric that look like sails of a small ship. Upon closer inspection, you’ll notice that the rest of the creature is made entirely of plastic tubing, what’s known as PVC. PVC stands for “polyvinyl chloride.” The white plastic tubing you’ve seen in thousands of bathrooms and kitchens is PVC. Upon even closer inspection, you’ll notice that the creature is made of PVC and nothing else. You’ll ponder that for a moment. Nothing but PVC. How does it move, then? Isn’t there a motor somewhere? Aren’t there electronics on the inside telling the creature when and how to move? You’ll become shocked and disoriented by the realization that the creature isn’t controlled from anywhere else or by anyone else. It is simply walking of its own accord, having a little stroll on a windy day along the beaches of the North Sea, as if it were alive.
