For example, one of the Google Heroes projects uses Google Earth to help track ele- phants in Kenya. The company posted a video on YouTube that included an interview with the founder of Save the Elephants. The camera operator shot the interview in front of a green screen, and the producer used stock footage of elephants tra- versing the African terrain. That stock video clip became the
