There are a few of these out there. Some copper, some aluminum. Some spin, or have a little variation to the design.
About the authorPast: Tolerated the U.S. educational system as far as a Bachelors degree. Favorite sports were skateboarding, windsurfing and pole vaulting. Worked on many jobs and projects, giving me a wide variety of skills and experiences.
Present: People call me a renaissance man. I still enjoy variety and being productive. Probably why artwork is one of my lasting activities. Snowboarding and hiking are my favorite ways to recreate with my amazing wife and sons.
