Blackle.com

I don't know if any of you have seen it before, but I came across Blackle.com the other day. It is the Google.com search engine, but it uses a black screen instead of white. It takes more energy to make a white screen than a black, and it is a little way to help energy costs. I mean, if we use it, we aren't going to see our power bills go down, but it is something small we could do if we are going to use the Google search engine anyway.
