Since 1998 Google has been displaying special logos called doodles that celebrate anything from celebrity birthdays to holidays to well-known events. Their first special logo was August 30 1998 when the two Google founders, Larry Page and Sergey Brin, decided to go to the Burning Man festival. They put up a different logo on their search engine that in a subtle, comical way told people they would be gone for a while. It took about two years before the next doodle appeared. Since then they have created and displayed hundreds of unique logos. See all of their doodles. Read the history of how it all started.
From time to time Google has a Google 4 contest where they invite children to draw a doodle that could make it to Google's home page. Some of them are amazing. They are in the process of choosing one from the many entries they received in their latest contest.
