The present application relates generally to a projection system and method for projecting content onto a moving performer. In one embodiment, the system includes a projector that projects light onto the performer, a position sensor, such as a camera and/or depth sensor that captures position information about the performer, and a computer that modifies original content based on the position information of the performer. The computer uses the position information to generate a mask, such as a silhouette, of the performer, and then modifies the original content based on the mask of the performer. The modified content is then projected by the projector onto the performer.
