The singing tree

I think this is a pretty good one, because the place where they put this sculpture is actually a place where people died long time ago, and it's creating sound that sound like ghost weeping, which is kind of scary and creates the right mood.

compared to my later posts music of the water and omfalos which creates beautiful sounds and make the park more interesting and beautiful, this is another kind of mood that will attract audience too, especially people who likes this kind of eerie moments.
