One of the most consistent things in modern life is the Google interface. Every so often they tweak it here and tweak it there but its always a Google logo with a search box on a white background. They’ve decided to highlight an energy conservation project called “Earth Hour” - where people are supposed to turn their lights off between 8 & 9pm today (March 29th 2008) - by making the Google.co.uk homepage all in black!

I think its pretty awful - more info on why can be found at http://www.google.co.uk/intl/en_uk/earthhour/.
