Doodle 4 Google 2012 has begun. Google invites artists in grades kindergarten through 12 to use their creative imaginations to redesign the Google logo. This year's theme is "If I could travel in time, I'd visit..."

The national winner will see his or her artwork on Google's homepage for one day, and will receive $30,000 for college and $50,000 for the winner’s school. The winning artwork will appear on a special edition of Crayola's iconic 64 box. The five Alaska finalists and the five runners-up will see their artwork displayed at the Anchorage Museum.

See www.doodle4google.com. Submissions are due March 23.
