A lightbulb that's not a lightbulb

Retro, as we've noted in this space, is the new new. And though it may be a bit premature to declare the incandescent lightbulb in that category, it seems we're getting closer all the time. That may be why Ecogeek is touting the GlowBrick phosphorescent light cube, which pays homage to the bulb's iconic form without wasting energy. It could also help scare away kids on Halloween when you run out of candy.
