Google changes it’s logo on their main search website from time to time. Previously they had put up an actual playable Pac-Man game as a tribute to Pac-Man’s 30th anniversary. Today’s doodle is actually a playable string guitar as a tribute to Les Paul.
So head on over to Google.com and scroll you mouse pointer to the guitar string to hear the musical note. This may look like a fun thing to do, but think about the Technology that goes behind it. Google search front page still loads fast with or without Doodles.
If you had missed out the previous Pac-Man doodle check out google.com/pacman. For an archive of all the previous Google logos, hen on over to google.com/logo.
