Google often hosts these "Doodle 4 Google" competitions in which Google encourages users to submit a doodle to become the homepage logo of Google for a day. Google has just announced this year's Doodle 4 Google in the United States and has kicked off the 30-day countdown to the March 22 submission deadline.

To make the competition more interesting and fun, Google has produced an interactive map that shows where submissions are coming from and which state has the most submissions. Google wants you to encourage fellow students and teachers to enter the competition.

One winner from each state will win an all-expenses paid trip to New York City in May for the awards ceremony. The contestant with the winning doodle design will win a $30,000 college scholarship and his or her school will win a $50,000 technology grant.
