There's a place owned by NYU, gated from the streets, and partially decked in cobblestone. Most days it goes empty, no one knows what it is or if they're allowed to be there. Some days kids hang out in the small steps in front of the doors and occasionally a small game of baseball will overtake the road.
This place is Washington Mews. The picturesque haven just north of Washington Square Park hosts a series of water pipes. The blue hued beauties demarcate the separation between buildings and as with their strong color, the water they carry is not gentle. The water has - with the help of time - driven the color off of the tube and traced it down the street.
Blue die runs from the drain into the sidewalk. The art of time and consequence has and will continue to add to the happy accident of the added art of the street.
