This was a Google Doodle Guitar shown on 9th June 2011.
Google on June 9th 2011 paid tribute to legendary musician and innovator Les Paul with an interactive Google guitar 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. Les Paul (née Lester William Polsfuss) was born June 9, 1915. He was an talented guitarist and an innovator who pioneered the solid-body electric guitar and a slew of other musical inventions that were instrumental in paving the way for rock-and-roll and defining the musical sounds that followed.
The Google logo has been transformed into a playable stringed instrument and can even make a 30 second recording of the music created using the Google logo.The Google Guitar logo lets users "play" the guitar by plucking the strings, and even lets them record their melodies.
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. After recording your masterpiece (the red light flashes to warn you when time is almost up), you can play back your track or share the link, generated with Google's URL shortener goo.gl.
