We've always liked the minimal Google.com homepage, but if you prefer a little spice to your search page (à la Bing), you'll like Google's new background image feature.
It's a simple enough feature that we've heard rumours of here and there: Just go to Google.com, move your mouse to the bottom left of the screen and click Change background image, and pick any image from Google's Public gallery, your Picasa web album photos or upload any image from your desktop. (As ever, Google is spreading the international rollout over a few days, so the feature may not appear immediately on your PC.)
