Ride a photon across the galaxy to your mind’s eye and experience how we see. “SEEING!” follows a photon’s creation and journey across the galaxy to a young stargazer’s eye. The viewer follows the photon into the girl’s eye, learning the structures of the eye and their functions, prior to taking a ride on the optic nerve. Seeing uses hemispheric 2D and 3D animations and video to teach how human vision works.
