Imagination is a sign of creativity

The creative aspect of pareidolia became known in the 19th century with the practice of 'klecksography' - the art of making images from inkblots.

Writer Victor Hugo experimented with folded papers and stains by holding his quill upside down to use the feather-end as a brush. Another practitioner of klecksography, German poet Justinus Andreas Christian Kerner, published Kleksographien (1890), a collection of inkblot art with accompanying short poems about the objects that can be noticed in the images.
