The Hyphae Lamp - Based on how veins form in leaves, each lamp is a completely one-of-a-kind design, 3D-printed in nylon plastic. The lamps are lit by eco-friendly LED's and cast dramatic, branching shadows on the wall.
This orbicular lamp by nervous system (via Flickr) is so interesting. It's gives off marvelous light and shadows. And it's a conversation piece of art!
