Nephelococcygia pronounced ne-f�-l�-kak-'si-jee-y� is a term used when people find familiar objects within the shape of a cloud. At one time or another, humans have looked up to the clouds and imagined shapes resembling familiar objects. The earth's atmosphere and the system of the weather are complex and self-organizing, the system itself is transient, permanent and fleeting, and transfixed all at the same time. Maybe an imagined letter of the alphabet. Or, it might be an animal or a person's face. This is called nephelococcygia and the word was first coined in the play The Birds written in 414 B.C. by the Greek comic poet Aristophanes.
