Each one-of-a-kind lamp is handcrafted in Philadelphia artist Robert Ogden's studio, with a playful consideration of how a lamp should function. Ogden has a knack for repurposing obsolete, industrial artifacts. He scours flea markets to find vintage knobs, gears, wheels and pulleys, yielding these rustic yet modern, eco-friendly creations.
