Google Doodles

Google does such a great job with their doodles (the artwork that occasionally replaces the traditional Google logo on their main search page). They celebrate everything from Christmas to Dr. Who to the birthday of a famous or otherwise significant person who has done some good in this world. Some doodles are interactive! I have always been impressed with the creativity of these doodles, and I appreciate their creative and educational value. Thanks Google, doodle on!
