• An entity passes the Hofstadter-Turing Test if it first creates a virtual reality, then creates a computer program within that reality which must finally recognise itself as an entity within this virtual environment by passing the Hofstadter-Turing Test. Spot the tricky circularity to this test? Players can only pass if they create a virtual intelligence which must then pass the test itself. And since that hasn’t been achieved by any human in history, nobody has yet passed.

And recently someone has embedded a pacaman game inside of Second Life for avatars to play and possibly show a form of intelligence by playing pac-man themselves.
