Google Logo By Kids

Google unveiled a steady stream of Doodles in 2009, including one with Mahatma Gandhi's face on October 2, 2009, the birthday of Mahatma Gandhi, which is observed by the UN as the International Day for Non-Violence.
On Friday, May 21, 2010, Google created a doodle to celebrate the 30th birthday of Pac-Man. It is their first (possibly the world's first) playable logo. The logo contains an accurate recreation of the Pac-Man game that can be played in a browser (it contains 255 levels). On Sunday, July 11, 2010, the 2010 FIFA World Cup Final was commemorated by a Google doodle showing the stadium where the match was played that night.
From time to time Google shows a special colorless logo on a local homepage in recognition of a major tragedy, often for several days. The design was apparently first used on the Google Poland homepage following the air disaster that killed President Lech Kaczyński in April 2010. A few days later, the logo was used in China and Hong Kong to pay respects to the victims of the Qinghai earthquake.
