Doodle 4 Google’s National Finalists public voting opens today

The Doodle 4 Google State Finalists were just named, and now it is up to the public to vote for their favorite to become a National Finalist.

The annual Google Doodle competition is open to K-12 students of United States schools. This year’s theme for the doodles is “If I could travel in time, I’d visit…” and the panel of guest judges features a slew of celebrities like Katy Perry and Jordin Sparks.

Google encourages people to take a moment and vote for their favorites to help decide who goes on to become the National Winner. There is only one vote per person per age group during the May 2 to May 10 voting period. A list of the State Finalists with options for voting is available on the Doodle 4 Google website.

“At the final event, one of the five National Finalists will be named the ‘National Winner of Doodle 4 Google’ and the national winner’s doodle will be featured on the Google homepage on May 18, 2012 for 24 hours,” Google explained.

Judging criteria and a description of prizes are also available online.
