Google is trying to be more fun and less evil, and what better way to do that than with happy background?
You can now customize the background of your Google search page, by choosing an image from a public gallery, or by uploading your own picture to serve as the background.
Pictures must be at least 800X600 in order to save as a Google background. The idea is rather nice, but makes for a longer load time. There's a price to pay for prettiness, I guess.
The results page stays white as ever – only the main page changes. Also, mind the fact that picture you upload become part of your public Picassa gallery, so watch it with the boobs and general porn. Or not.
