Some of the biggest ideas in the world happen overnight. While CNN ireporter Chris Morrow covered the behind-the-scenes activity of the 2009 Toyota Grand Prix of Long Beach, the last thing she expected was to stumble across one man's plans to paint the largest picture of planet earth. But 24-hours after boldly announcing his goal to do just that, renowned environmental artist Wyland put the finishing touches on "Earth: The Blue Planet:" a three acre interpretation of our world atop the Long Beach Convention Center. Using ingenuity, elbow grease, and thousands of gallons of eco-friendly paint, the prolific artist turned a dusty, dry roof into a watercolor painting that can easily be seen from the upper reaches of the stratosphere. "Wyland: Earth Day" takes you inside the creative process behind the artist and his mission as told by the ireporter who chronicled the entire event.
