I really love seeing through water droplets. They are like little luminous globes, and worlds unto themselves, until you realize that what you are seeing is the world upside down through them. That is worth staring into! I first disovered this years ago when I took a picture of raindrops through the windshield of my car waiting at school pickup, and once I enlarged it realized I was seeing the trees in front of the car. These water droplets greeted me this morning outside my window.
