"Eco-Pop" created by Li-Fen Anny Chang, assistant professor of visual arts and design, received the "Sustainable Design-Professional Level" award at the 2012 International Textile and Apparel Association conference.

Chang collected soda tabs for five years for her dress, which took a year to construct, to promote environmental awareness. "Eco-Pop" is on exhibit at the Goldstein Museum of Design in St. Paul, Minn. through May 26.
