Say what you will about Google. They sure do like to have fun with their logo. It's always fun to go to the site and see something new.

Today's visitors to Google.com are greeted by swirling multi-colored balls that come together to form the logo (and dance apart when you wave a cursor over them). Pretty neat, huh? What does it all mean? Well, no one is quite sure.

For my money, though, they may never top Pac-Man.
