This has to be the coolest application that I have seen yet. The TouchGraph application allows you to visualize your friends that are connected to at least one other person in your network besides yourself. Ultimately this ends up displaying your closest friends through an amazing interface. Zoom in and view the pictures of your friends, drag networks and people around, and see which friends are the most connected to your other friends. This is hands down one of the sweetest applications I have seen yet. You can also visualize which of your friends overlap your various networks. If you are part of a lot of networks (and connected to those networks on Facebook) this application will surely keep you entertained for a while. So if you want to visualize your Facebook relationships, go grab the TouchGraph application. A demo video is posted below.
