Google Logo By Kids

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.
