"Google today is paying tribute to legendary musician and innovator Les Paul with an interactive logo that lets you play a virtual guitar, record it, and then share your composition. The special Doodle is in honor of what would have been Paul's 96th birthday."
and..."You can strum the virtual guitar using your mouse or use letters and numbers on your keyboard. U.S. users have an added ability to use a black "record" button to save a 30-second song."
Cool eh? I happened on it by accident when I pressed a wrong key. Just, ahem...google google to find today's search page. :)
