Light as sculpture? Artist Dylan Kehde Roelofs, makes hand-blown bulbs that are "a reaction against the soulless glow of low-energy bulbs."
Priced between $200- $1,300, these are more than mere lightbulbs but things of beauty. The artist will replace the first filament at no cost, but anticipates that each filament will give you thousands of hours of light. Via: Boing Boing Gadgets
