This 20 foot / 6 meter stainless steel sculpture has been at the corner of 8th and Washington since 1976. Its title is Synergism. Quite a few years ago I represented one of the two co-designers. Before I knew this was his work he simply told me that he was a sculptor. I asked him what kind. "A great one!" he immediately shot back. You can form your own opinion. He's got several pieces around town.
