If you would like to play a little and create something creative you can start from David Ngo idea. He used an illuminating object, some fabric, zippers and created the Zipper Ligh. This wall hanging capitalizes on the inherent capabilities of ordinary zippers to provide varying levels of brightness, a unique and gratifying user interaction, as well as an expression of revelation, discovery, and mystery. The light might not be so powerful, but the effect is worth a try.
