A couple of months ago, we announced the Doodle 4 Google art competition and invited students in grades K-12 across the U.S. to redesign our logo around the theme "What if...?".

Since then, more than 16,000 kids across the country have been busy creating their doodles. It's been a lot of fun for us and the kids (see for yourself in this video):

Today we're excited to announce the state finalists and 40 regional winners. The thousands of wonderful entries made judging difficult, but with the help of experts at Young Audiences, Teach for America and reporters from across the country, we've managed to narrow the field to the very best.

Now it's your turn. Starting today, you can vote for your favorite doodle. Your votes will determine the four national finalists. Just make sure to vote soon: you only have until May 18th. The national winner will be announced and the winning doodle will replace our usual logo on the Google homepage on May 22nd.
