Even if you are not into #dogurineart , YET, and believe me, I can understand why that may be, you’ve got to admire the abstract composition, heightened by the addition of the wet brown to the variegated concrete.

I am no fan of dog urine.  Believe me.  It’s kind of disgusting.

But after years of living in Manhattan, walking the city, looking at random patterns on sidewalks and seeing the effects of many things, from oil sheens on wet pavement to cracks simulating medieval  castles, I have begun to notice splotches of wetness against the dryness.  The liquid runs as liquids do, no doubt following the laws of physics, but with an additional element of unpredictability, as always happens when living things are also involved.
