a blot made with ink

a symmetrical but otherwise abstract pattern of shapes created by folding liquid ink into the vertical fold of a piece of paper. The Rorschach ink blot test is a psychological projective test of personality in which a subject's interpretations of ten standard abstract designs are analyzed as a measure of emotional and intellectual functioning and integration. The test is named after Hermann Rorschach (1884-1922) who developed the ink blots, although he did not use them for personality analysis.
