Earth Hour

So tonight they are having Earth Hour. Asking everyone to turn off their lights from 8:30-9:30pm tonight, local time. Giving an hour in your home and 24 hours for the world. Pretty neat. They have an Official Website and a crazy video. It senses whether the camera on your computer can see light or not and changes the video you see. Pretty neat. More on this on the linked websites or Gizmodo
