Dicking around and just noticed if you go to Settings --> About Tablet and then tap the Android Version rapidly (must be quickly) it will take the tablet to a nice little surprise.
EDIT: Just did this again and the results aren't the same. First time, it brought up Jelly Bean and a big bean then filled the screen with a bunch of little jellybeans you can touch and throw around. Now it only brings up the big bean.
