Grace Moon is only 12, but her artwork has already been seen by millions - or whoever happened to stumble upon a little website called Google on Monday 22. As the winner of Doodle 4 Google, a youth art contest sponsored by the mega search engine, Moon's logo design - a colorful oasis anchored by a beaming sun - graced the iconic Google homepage, visited by about 100 million people a day.Moon, who's finishing sixth grade at Canyon Middle School in Castro Valley, Calif., titled her design "Up in the Clouds" to express a world in the sky. "when I look at the news, I see all the disasters and problems in the world," says Moon, who beat out 16,000 contenders to win a $10,000 scholarship, a laptop computer, a trip to the Google headquarters in Mountain View, Calif., and a $25,000 technology grant for her school. "I though, what if there was a place without these fearful things? I thought of an ideal place that could have no violence, disasters or discrimination. Everyone could live in a place high above the clouds."
