Kind of like a hall of mirrors, only you aren't constrained by optics, or
reflections, eh? Or better yet, maybe you CAN reflect. Maybe you could
also introduce the concept of time, so not only does the environment change
depending on where you are, but in relation to time as well. The
user's perspective point could also be traced, and they could turn around
and look back at themselves coming toward their present point.

So our discussion has changed it's subject, as we walked through it, and
just now it's turned self-referential. If I wait here long enough, I should
soon see you reading this message, and replying to it, just as I
described in the paragraph above. Surreal!
