Suppose your life/program is represented as a high dimension manifold,
then it would be possible to compute a given moment by selecting a
point this object's the surface.  The memory/state information would
be relative to that point, but not necessarily require iterative
calculation.

I've thought about this using the frames of a film - each 1/24 of a
second contains stateful information about it's placement in the
sequence.  For a movie you know well enough, you could probably
resequence a random pile of film clips from these clues (within some
threshold of accuracy: 1/24 of a second doesn't allow a great deal of
variation from frame to frame)
