A pointing device includes a casing having a lens received in the first end thereof and a battery received in the second end thereof. A motor is received in the casing and has a shaft to which a transparent disk is co-rotatably mounted, a plurality of pictures imprinted on the transparent disk. A control device for actuating the motor is received in the casing and connected to a button on the casing. A laser beam generating device is located between the control device and the transparent disk, and aligns with the pictures when the transparent disk is co-rotated with the shaft so as to project a motion picture on a remote wall.
