Net-Art application by Timothy Grover uses your Facebook profile and transforms it into a unique 3D experience:
F∆CEWORLD is a website/app that allows users to navigate through a 3-dimensional realm of their own personal Facebook history. Each individual user that logs into the app will be able to see only their own data “objectified,” which makes each experience uniquely specified to that user.
Works best with Chrome - try it out for yourself here
[EDIT - the project also has a Facebook page here]
