Discovery World Milwaukee at Sunrise - tree and sail thingamajigs - Nov_2007 - image by Mike Fisk
Here's a pic from the morning (11-23-2007) when I started taking photos of the Falcon Chinook 34 stranded sail boat. These are large tree-like sails with small coin-like objects on them. When the wind blows the coin-line ornaments rotate in concert to let you see the wave patterns of the wind. It fascinates the heck out of me. There are wheels at the bottom of the masts that allow you to turn the sails. Also there are wooden benches in the same park with drumsticks attached to them that you can play like a xylophone. All very cool.
