Be sure to check out the snowglobe on the nXe. You have the ability to put all of your friends avatars inside of a snowglobe, and then shake them up and down.
This application, which is available on the Spotlight section in most regions, is a fun little application, even though it is extremely random and useless. You can still have the fun of putting most of your friends inside of the ball, and shaking them until your hearts content. If all of your friends can’t fit inside the tiny ball, you can swap them out, and bring in some more of your other friends.
