The Rubber Band Lamp shows just how versatile elastics can be. Not only do they hold and group things together, they can look good while doing it as well. Of course, I'm sure these bands are functioning fully for looks rather than any other practical reasons.
Designed by Orchard Studio, the Rubber Band Lamp was exhibited at during the London Design Festival. Interestingly, you can customize these lamps by rearranging the elastic bands yourself.
