Apparently there are some easter eggs hidden in the Gingerbread 2.3. Go to settings>about phone and then keep taping on the android version number and "Zombie Art" by Jack Larson will pop up. Also, if you have CM7, you can also repeatedly tap on the mod version number and it will reveal another picture by Team Douche. Post if you found any others!
