Something Tiny and Amazing

While I was taking Shelby out tonight, I came across a dead leaf that appeared to be hovering in mid-air about four feet above the ground, just off the sidewalk in the park. It was hanging from a tree branch, attached to a long piece of silk from a caterpillar or maybe a spider, gently twisting and floating around in the breeze. I left all my gadgets at home, so I'll just have to remember it instead.
