Vollis Simpson's windmill-powered whirligigs

Some time ago, I posted a YouTube video about Vollis Simpson, a man who has made a park full of windmills and whirligigs. There is a great web site with more about the man behind it all. The site also features a detailed virtual tour of his wind-powered mechanical park.

Here's a link to From Windmills to Whirligigs brought to us by the Science Museum of Minnesota.
