Flowing Capes

I think I nice product would be capes flowing at various angles and wind speeds. I could see myself adding a cape to a sitting character in a Star Wars-type video as he jets off across the desert on a speeder-bike, or a superhero as he flies through the sky or slowly descends out of the air. I think this could be a useful product. Perhaps the capes could be gray (or whatever color would be easiest to color grade to any needed color).
