I'm always trying to think of great recycled materials that could be used for making affordable modern furniture and lighting. While cardboard doesn't seem like the most likely medium to create great lighting, the folks over at Graypants are out to show that it absolutely works. Using salvaged cardboard they sculpt beautiful modern lights that have a wonderful natural glow to them. You can purchase their wonderful lights from Velocity Art and Design in either a hard wired or plugged version with prices starting around $135, which is pretty reasonable. Of course if you are feeling a little more daring, and have access to some scrap cardboard then the possibilities are endless.
