The building blocks of life for Robert Jefferson Travis Pond’s animals are metal scraps, taken from discarded motorcycles and other heaps of seemingly obsolete material. Welding gas tanks, pipes, and gears, he creates life-sized creatures of several types. The Portland-based artist’s Steel Pond Studios focuses on taking objects that are “part of human history” and injecting new life. Half of what Pond does is collect materials, he says. And then, the creatures begin to take shape.
