Dreaming of a Green Christmas. Inhabitat has a great post on a great alternative to traditional holiday lights:

For some, the eco-benefit isn't enough. Many of the commenters said "Bah humbug!" the light cast by LEDs is "eerie and cold." Do
ATers have experience or opinions on LED holiday lights? —aaron
