It's enough to make me wish I'd hung on to mine. Faced with a mountain of CD jewel cases, industrial designer Josh Owen came up with a way to repurpose them:
"With the steady dematerialization of CD based data storage, much of the packaging associated with these items has begun to turn up in landfills. With ecology in mind, this project investigates repurposing the industrial artifact beyond its originally intended functionality. The jewel case possesses specific transparent and opaque parts, which provide interesting lighting opportunities."
Owen, who's currently Director of the Vignelli Center for Design Studies at RIT, designed the CD Chandelier back in 2005. You can see more of his work here.
