The New Google Look

I woke up around 8AM today and sit in front of my laptop. I thought I have a Computer Virus as I saw Google.com Homepage turns all black. So I tried http://www.google.com.ph, its all white. I also tried http://www.google.ca and it turns out black too. The reason why? Its because of EARTHHOUR visit this link http://www.google.com/intl/en/earthhour/
Visit EARTHHOUR’s website http://www.earthhour.org/
