Google Les Paul Doodle

Okay.  This might very well be the coolest Google doodle to date.  This interactive doodle commemorates Les Paul's 96th birthday and allows you to play actual songs.

You can play by moving your cursor over the strings or by using the keyboard.  Although the doodle is no longer displayed on the Google home page, you can still use it at http://www.google.com/logos/2011/lespaul.html .  Good work, Google!
