My original thought for the AI in MekArcade would be they manifest either as a real physical android acting as a avatar or as glowey, non corporal entities like Cortana in Halo. Both ideas are based on an AI model within a conventional map. In the music post there is this map (sorry not sure who it's is) that could be the 'mental space' of an AI, it's a bit Matrix like, but it did stimulate me to think about using a map to represent the mind space of an AI

The idea of communication using virtual environment is a very common one in SF writing, underpowered human wetware needs a familiar metaphor to communicate with AI or even Aliens (Carl Sagans, Contact used it) Other than communication, a map could be used hacking into an AI mind or as a way of representing AI in hyperspace.
I know there are other examples of 'non representational' maps in the Cube world and I would be very interested in seeing some. So if you have previously posted such a map, put a link up here or if you haven't yet posted your masterpiece do it here.
