Here's a lesson to all the interns of the world: Take some initiative and you very well may get rewarded. Take Google employee Denis Hwang, for example. While interning at the world's largest search engine, he began redesigning the Google logo to mark holidays and other major events. The designs, known as Google Doodles, caught on, and not only did he get a gig, but Google also decided to continue the tradition. After Google recently marked Mother's Day with a cool Doodle, we went back into the Google vault and put together a list of our past favorites.
