When Google went ahead and updated the Android website not all that long ago, they had some easter eggs built into the site at the bottom. Previously, you could go ahead and make Bugdroid do the moonwalk, wave hello and juggle among other things. If you head on over there now though -- there is a fun little snow ball tossing game in place of the previous easter eggs. No telling how long its been that way but, it's the little, clever things that make us happy.
