ABSTRACT:
SUMMARY OF THE INVENTION
An image/message display device includes a ceiling fan suspended from the ceiling. A controller for the display is mounted on the ceiling fan and includes hall effect sensors for determining the rotational speed of the fan. LED panels are mounted on each of the blades for creating the image/message as the ceiling fan turns. Aerodynamic covers are placed over the LED panels. A dark, non-reflective background may be suspended behind the LED panels to enhance the view of the image/display.
