I just cleaned up an old Welding sculpture I made from college back in 2005. My goal with this sculpture was to have many, many weld joints to practice. I love how it looks like some crazy Roller-Coaster sketch.
I put the image in paint.net to make it easier to see.
And then I took away the background noise. Can you see one spiral that makes me think of the Fibonacci Spiral?
You can rotate this piece 380 degrees and see all kinds of new lines!
