Abstract: A rotating changing image display carries an image group and decoder screen that displays frames of the image group in a sequence determined by direction of rotation. A sequence of frames shows subject matter with identifiable directional motion. In order to ensure the sequence of frames will be displayed in proper order in accordance with the identifiable direction of motion, the display is mounted to a directional rotator. The rotator is wind driven. Airfoil structures of the rotator are configurable to drive the rotator and the carried display in the identifiable direction of rotation.
