Grate art

I stole the title of this entry directly from here. New York City has subways rushing through tunnels. It’s like pistons inside cylinders. Air gets compressed ahead of the train, and needs to be vented to the outside so it doesn’t blow passengers off the loading platforms. They vent the air through grates on sidewalks. As a train passes below, air is blown up and out. What a neat resource, thought the artist Joshua Allen Harris. Let’s use it for something. Which he did.

Almost as interesting as what a subway vent did to Marilyn Monroe’s dress in the movie The Seven Year Itch.
