Everywhere

Hermann Rorschach, the Swiss psychiatrist who invented an eponymous test, called the Rorschach.

In a real Rorschach Test, a patient is asked to

describe what he sees in ten standardized blots--some black and gray, others with patches of color. Trained professionals then measure the responses against a set of established norms, interpreting the interpretations to unearth dark secrets about the subject's personality, intelligence and sexual proclivities.
