From the artist’s statement: “Images of faces hold little ability to communicate the totality of a personality. The essence of a personality is not something that is stored in a static two dimentional array of dots, grains, or pixels. Rather, what is stored are subtle cues which signify base personality traits, such as a curl of a lip, squint of an eye, or pursing of the lips. These can work in series or combinations to suggest complexity of description, but ultimately, amount only to a caricature.”
