The Most Beautiful Oil Leak I've Ever Seen

I was walking home from the train station, crossing through a parking lot when I saw this amazing scene. It was an oil leak on the blacktop. Yet, this wasn't any ordinary puddle. The oil mixed with the rain water to create this psychedelic design. First I shot it with my iPhone, then I used my Canon 40D with a 17-40mm lens. I figured I probably looked ridiculous photographing the parking lot, but I didn't care. I was amazed at how beautiful something like oil could create. I made six more exposures before continuing on. Here is my favorite.
