Case Discussion
Pareidolia, the recognition of familiar forms in natural phenomena (e.g. cloud formations, tea leaves) or while interpreting radiological exams, is a well-known phenomenon - see the Rorschach radiology article for many more examples.
The word "pareidolia" derives from the concatenation of the Greek words παρά ("beside") + εἴδωλον ("form, shape").
