Rings - Facebook visualization application

Rings is an interactive visualization of the Facebook stream. It organizes all your friends’ updates/posts on Facebook in a graphical way, and provides a general awareness about your friends’ activities by visualizing time patterns of posting. Then, users will become easily aware of who are the active users among their friends, who post many posts, how popular their posts are, who have stopped posting updates for a while and have become lurkers, etc.
