quietrevolution info about this model:
Unlike other renewable energy sources, quietrevolution is also available in a unique model capable of creating a striking visual display that is part illuminated billboard, part artwork, part renewable energy device.
Light Emitting Diodes (LEDs) embedded in each of its three S-shaped blades fire in sequence as the blades rotate, painting a video screen that appears to hang in the air. This full colour and motion image is clearly visible day and night.

Europa commented on this; it's actually an advertising display model... it could flash "Eat at Mhom's", for example.
