artificial wind chimes

Version 1 is pretty simple: You have a fan that causes the regular wind chimes to chime.

I envision antix's idea as different with no wind at all just chimes run on batteries. (Or batter as alx pointed out). So even version one would be a uniquely new idea. But then comes version 2.

Version 2 are chimes that CAUSE artificial wind. Here more innovative thought is needed, since these chimes are CREATING the wind. Of course if there already is a naturally blowing wind available you can switch the wind generation function off and just use them like any other wind chimes you may or may not have outside your home.
