Styrofoam is widely used because cheap and disposable, if not entirely recyclable. But when you heat-shrink it and fashion it into a giant ball, its value skyrockets to $700. High concepts!
Designer Paul Cocksedge originally created the Styrene lamp when he was in school 10 years ago, and now he has released it to the masses. Centered around a fluorescent bulb, holes are intentionally left open for light to escape and create strange shadows against any surface it illuminates.
The finished project is surprisingly nice, if disproportionately costly. Maybe I'm just an idiot, but intuition tells me that one could generate a passable replica as a weekend project for considerably less money. [Paul Cocksedge via Dezeen]
