[spam] for the n-dimensional space approach, i'm thinking on the idea
   of agents being fixed in some dimensions, able only to navigate others,
   and using sum of axial distances rather than the sqrt of their squares
   to measure.  this could help develop experience around things having
   conceptual, similarity, and other forms of distance that we can't
   navigate; unsure.  I was thinking of mapping things like cameras or
   chat windows to different spaces in the virtual model world, and how
   their physical location may not be well represented: the systems would
   learn it.  another idea is including "portals" inside the coordinate
   environment, fixed things that communicate information with other
   coordinate environments.
