When you see items with an artistic eye, you see objects as they can be, not necessarily as they are. A plumber might see a piece of a pipe as an instrument for the job, a janitor might see it as a piece of debris, while an artist might see it as a limb to a robot lamp. The purpose of a pipe depends upon the eye of the beholder.
Ordinary pipes crafted together to become robot lamps. Art is in the eye of the beholder.
