A few years back, I did some work for a roofing company. Of course there is metal around for flashing, etc. Some one there must have had an eye for the art that is present in metals because someone had made a wall decoration from metal. Small pices of metal had been cut into shapes of leaves. (They must have used some type of heat to make the cuts; the edges were all jagged like real leaves) Then the leaves had been welded onto some type of rod (all twisted and turn to form a branch) There was one main branch with smaller branches "growing" from the main branch. I could certainly see a design such as this being created from cooper and hung outside where it could turn all those wonder tones.
