This is a piece we have on our back porch. A welder friend will just grab scrap from his pile of scrap from paying projects, and make something up. His only "rule" is not not use any metal that is not from his scrap pile.
This one has toes made of ball bearings, and a mud dauber started making a nest for a baby in one of the eyes. Now both eyes are closed up with mud. Since mud daubers gather up spiders to stuff into the nest, we leave em alone.
