Rain Spot Shadows

It had started raining fairly hard this evening, so I was sprinting as best I could through the dark parking lot to get to my car. I had parked right under one of those odd lights we have on the parking lot roof, so when I jumped into the car and paused to catch my breath, everything was polka-dotted with moving, wiggling shadows, cast from the drops on the windshield and the light directly overhead. It was most pronounced on the bright, yellow sweater I was wearing. Sometimes I could see long, snake-like lines of shadow as groups of drops congealed into a critical mass and slid down the glass.
