Windmaker
Windmaker brings wind to the Web.
Windmaker is an ambient weather widget that applies the current wind conditions to (almost) any Web site. Visitors are invited to submit a post code and a Web address. Windmaker uses the post code to fetch live wind conditions for that locale. It then parses the submitted Web site into individual pieces such as text blocks and images. Finally, Windmaker sets these pieces in motion according to the current strength of the wind.
Tested in current versions of Safari, Chrome, Opera, and FireFox for Macintosh.
