Tubing statue

This statue is located in the center of Denver, Colorado. It caught my eye since the entire structure is made of metal tubing. Metal smiths, including myself, use tubing extensively, although on a completely different scale.

After a short search on the web I found out that the statue is by artist Robert Mangold. He has an impressive body of works yet I didn’t find any other work that was also based on tubing as a building blook.
