Google has just opened up the 2013 Doodle 4 Google competition, and are currently accepting submissions. This is the 6th year that Google has held the contest.

Each year, Google asks student aged K-12 to create their own Google Doodle. The winners are broken into grade brackets, and national finalists receive a small prize. The grand prize winner always receives tens of thousands of dollars in scholarships, grants, and other cool swag.

This year’s prompt is “My Best Day Ever…”

“The judging starts with Googlers and a panel of guest judges. This year our judges include journalist and TV personality Katie Couric; music maestro Ahmir “?uestlove” Thompson of The Roots; Chris Sanders, writer and director of Lilo & Stitch and How to Train Your Dragon; and Pendleton Ward, creator of Adventure Time; among other great creative minds,” says Google.

On May 1st, once the state winners have been selected, the public vote will open. Winners will be announced on May 22nd.

The winner of this year’s contest will win a $30,000 college scholarship, a $50,000 technology grant for their school, and will see their doodle appear on the Google homepage for a day. Pretty sweet deal.

Below is last year’s winner; Second-grader Dylan Hoffman’s response to the “If I could travel in time I’d visit” theme.
