A device for manipulating visual images such as those provided by a common slide projector, employing an audio transducer apparatus for controlling positioning of a mirror in response to vertical and horizontal control signals. Numerous control signals indicative of human operator movement are developed by a joy-stick control apparatus for selective application as vertical, horizontal and brightness control signals to the projector transducer system. Selectible automatic control capability is also provided by means of oscillator circuits, float circuitry and automatic brightness control and blanking circuitry.
