rorschacht or pareidolia

Via Laughing Squid comes this growing Twitter gallery of objects of objects that appear to have anthropomorphic faces, whether by chance or accident, like the mesa that became the Face on Mars due to the camera angle and the human tendency for identification. There are a lot of really good ones but among my favourites is this hungry, hungry helicopter with an appetite for soldiers at the link and the more abstract extensions of the occurrence. It was really weird when an alien face appeared in my beer glass and was quite persistent or the montage of the three wise men on our freshly painted wall, though I do not have convincing photographic evidence. What examples do you have?
