Google Maps Labs introduced

Google Maps Labs is an opt-in feature that introduces several new nifty functions and fun into Google Maps. The Google Maps Labs icon is a small green beaker in the upper right corner with the word "New!" to the right of it. Although you do not have to have a Google Account to add these features and fun things like a geography guessing game to Google Maps, in order to save the changes between browsing sessions, you have to log in to your Google Account.
