Found Object Art

This intrigued me as I noticed it on this site.

How much art could be created from the "junk" that we see around us?  What about metals and rusty things that we see piled up around our communities?  How could they be used,remixed and reborn as art?  Open your eyes today to see the potential in things around you.
William Christenberry's work, rooted in his Alabama upbringing, is born of things familiar and deeply felt. Whether in paintings, drawings, sculptures, constructions, found objects, or photographs, each expression gathers meaning from a specific time and place through which we experience one man's collected and recollected journeys. They are meditations on universal themes of loss and isolation, memory and comfort, creation and change.
