LED Lighting?

This is an interesting article about LED lights replacing regular light bulbs. Even aside from the fact that such an old technology as the light bulb could be replaced, there are a couple of cool things in the article. First, LED makers are developing lights that could take the place of neon lights at stores and bars. One manufacturer has designed LED's set in plexiglass that can withstand a shotgun blast. That would make a good commercial.

Second, the article mentions that Qantas (the Australian airline) has installed LED's in its first class cabins that can change in color. The airline turns the lights blue when it's time to sleep, reminding one of when John Trent woke up screaming on the bus in In the Mouth of Madness -- in blue light.
