Brandon and I made these copper and bamboo wind chimes a while back. We made them with green bamboo. I've been waiting for the bamboo to age before posting a picture of them. They have a lovely sound. Only the center piece doesn't seem to be quite big enough to make it sound often unless there is high wind. Right now it is a fat piece of bamboo. If I can find a piece of wood that is not too heavy but wide enough to make it clink (can't really say they chime) more often then I'll replace the center piece.
