In a vacant lot near where I work is a world globe made from a large iron mooring buoy.
It is mounted on a trailer and was used at some time as part of a parade float.
Now it tells the weather.
When there is a glare on it--the weather is sunny.
When it's wet--the weather is rainy.
When it's tipped over--the day is a bit breezy.
Right now it looks like this.
I think it's pretty accurate, don't you?
