How cool (HAHAHAHAhahahaha! I kill me.) is this?
Yeah, that's a face in an icicle. It's an incredible example of pareidolia, one of the best I've ever seen (nothing will ever beat Lenin, though). Yahoo has a funny article about it, saying tongue-in-cheek it's Jack Frost. I had to laugh; after all, who would think that some random collection of shapes that happens to look like a face would actually be a real manifestation of a supernatural entity?
