Rubbish in a new light

Out walking, on a block cleared for building, there was some dumped rubbish.  One item was a crushed wing mirror from a car.  The sun was reflecting off it, so I switched my camera to macro auto focus setting (1 area) and set it down next to the pieces.  Aperture Priority f/2.8, 100 ISO, white balance on daylight, and I had this interesting shot that looks like a blue glass mountain.
