New York's Museum of Arts & Design (at Columbia Circle) hosts an exhibition devoted to art using paper - October 7, 2009 - April 4, 2010.
One artist's work in the exhibition, Ferry Staverman, creates cardboard constructions which are wonderfully whimsical, delicate in appearance and bio-decorative in feel. I love the grouped composition within this photograph thanks to the variety shape and size.
I would run, knees high, to see this exhibit if I were in NY.
