Google Doodles have been a way for the search engine giant to honor historical figures and remind its users of important dates. The first Google Doodle was in honor of the Burning Man in 1998 which only showed a stick figure behind the second "o" in the Google logo. Since its humble beginnings, the Google Doodle has become more inventive and sophisticated. From simple images, the Google Doodle has evolved to interactive ones that amaze and delight users.

Pac-Man Doodle

On May 21, 2010 Google Doodle released its first ever interactive doodle with a fully functioning Pac-Man game to celebrate the game's 30th anniversary. There were 255 levels created, and bored employees, students and the young-at-heart played the arcade classic much to the dismay of employers and universities everywhere.

Jules Verne Doodle

In celebration of Jules Verne's 183rd birthday, Google turned its browser into a submarine on Feb. 8, 2011. Users could plunge 20,000 leagues under the sea with the Google logo acting as a window to the sea.

Les Paul Doodle

If there was a Google Doodle that could rival the amount of time wasted by the Pac-Man doodle it was the Les Paul Doodle. The Google Doodle went live on June 9, 2011 to celebrate Paul's 96th birthday. The interactive guitar could play tunes and many budding musicians tried their hand at creating a passable impression of a guitar riff.

Stanislaw Lem Doodle

This European Google Doodle released on November 23, 2011 to honor the Polish science-fiction author Stanislaw Lem is one of the best interactive Doodles the company has released. The Doodle is a puzzle featuring the eye-popping visuals of Sophia Foster-Dimino inspired by Daniel Mroz's artwork. The viewers can move through levels in a story inspired by Lem's book "The Cyberiad". The Doodle's length and ambition is more than anything Google has done before. Try to spot all the hidden Easter Eggs in the doodle.

Freddie Mercury Doodle

In order to celebrate the 65th birthday of the late Queen singer Freddie Mercury, Google released a 100-second music clip that shows the flamboyant performer at the piano playing Queen's "Don't Stop Me Now". The Mercury tribute went live on September 05, 2011.
