Doodle 4 Google is a contest where students in the United States are invited to use their artistic talents to think big and redesign Google’s homepage logo for millions to see.

This year, Google is asking students to exercise their creative imaginations around the theme, "If I could travel in time, I'd visit …"

One lucky student artist will see their artwork appear on the Google homepage and take home some cool prizes – and as a special bonus, the winning artwork will appear on a limited edition of Crayola's iconic 64 box.

The National Winner will have his or her doodle featured on the U.S. Google.com homepage.

He or she will be awarded a $30,000 college scholarship to be used at the school of his or her choice, a trip to New York for an event on May 17, 2012, a Google Chromebook computer, a Wacom digital design tablet and a t-shirt printed with his or her doodle on it.

Google also will award the winner's full time school a $50,000 technology grant toward the establishment or improvement of a computer lab or technology programming.
