The Witness is a steel encased infinity mirror box with small video monitors and a single prism.  The box is entirely enclosed, except for a 2-inch peep hole to see inside.  The peep hole is the same size as a camera lens of a DSLR Camera.  The viewer turns into a voyeur; someone involved only as a witness, implicated merely by the act of viewing: an observer, a spectator, a bystander, an eyewitness to events.
