This is what I call a "RoBonzai" tree. The piece is called "Juxtaposition" and represents my [tongue-in-cheek] belief that all things are alive in their own way, whether we understand it or not.
It is kind of like a Gem tree, but with a small twist...the tree is actually a solar collector. It powers a small motor with some silver faerie bells attached to the output shaft.
It will give a subtle "jing" every few minutes in normal light and every few seconds in direct sunlight.
I'll post more pictures later.
