Mystery Quickie

I'm going out to a play tonight - to see #2 Son's girlfriend in The Pirates of Penzance - so this is a quickie. It was a quickie when I took it as well. Just a shot of a step on the back stairs going up to the Live Arts office this morning. A step that had been used as a place to apparently spray paint three blocks of... something. So their outline is all that remains. I did give it a tiny tweak in PS to make it more colorful - or give it some sort of something. The extra - should I manage to get it to load - is the original iPhone shot.
