Exploratorium, San Francisco

Artists and photographers know human faces aren't symmetrical; it's a surprise to most face owners. By mirroring your face's right and left side, two "perfect" versions are created. PBS NewsHour demonstrates below. I created this exhibit for the Exploratorium's gallery of Human Phenomena which I discuss in the ABC News interview.

Inspiration came from a conversation with David Presti, a neurobiologist, who explained that emotions tend to be expressed more strongly on the right side of our faces. Even rhesus monkeys and domestic dogs tend to look first at the right side of human faces.
