ExitReality is like any 3d world, you create an avatar, you walk around and chat with other avatars etc. There is one interesting twist , it automatically converts each webpage into a 3D world. Links appear, pictures are framed etc. As a result your avatar runs around a lot like the old classic Sci-fiction movie Tron. In this video, this 3d world seen here is automatically created from NUS catalogue search result page (ENCORE) (less info)
