I've always wanted to "fill the outlines" of a structure to have it "live" in my space with me/us, and one day aluminum popped into my head at Home Depot@ (I was looking at it, not exactly a revelation). When Dave suggested how to put the quill into the feathers it started to "come alive".
Thanks Dave. The wind turns it on it's post on top of a 3ft concrete pillar. Bruce Turner
