Sometimes in the high-stakes world of commercial design, even the best ideas get shelved. That happened to Will Prindle about 10 years ago when he was vice president of design and development at Forms + Surfaces. His idea and designs for an explosion-resistant public trash receptacle were scrapped. Now an assistant professor of industrial design, Prindle has retrieved his discarded idea from the corporate junkyard. And he intends to see it through to the marketplace.
