An apparatus and method for a laser light display projector for projecting a beam of laser light so as to produce a light pattern forming a visually perceptible light image includes a laser light source generating a substantially parallel light beam; a diffuser positioned so that the light beam passes therethrough prior to forming the visually perceptible display, the diffuser having a diffusion pattern effective for diffusing the light beam by a predetermined amount; a rotary actuator bearing the diffuser to thereby impart a rotating motion to the diffuser so that the diffusion pattern rotatably intersects the light beam; and a controller operatively connected to at least the rotary actuator to control rotational positioning of the diffuser in the light beam.
