Self Portrait

As I finished work this morning and was leaving the bus terminal to go to my car, I saw this on the pavement. I see oil spills all the time there, but I've never seen one do this. As I was photographing what must from a distance have appeared to be nothing on the pavement, apparently I must've looked goofy enough to attract attention, because several people came over to see what was so engrossing. One of them even whipped out her camera and joined me :)
