Google announced our third annual Doodle 4 Google contest in the U.S. Google doodles today. Since 2008, Doodle 4 Google has given K-12 kids the opportunity to create their own logo and have it displayed on the Google homepage for hundreds of millions of users to enjoy for a day.

In addition to the winner’s art appearing on Google.com on May 27, 2010, they’ll also receive a $15,000 college scholarship, a laptop computer and a $25,000 technology grant for their school.
