The changing Face of AuT

Here's a chapter or two from the second edition of Spirals in Amber:
Time (as we experience it) may result from the existence of CT5 even though matter is CT4 because with CT5 a point of reference is created.
In relativity, space time is changed (bent) by gravity.  In NLC the amount of gravity (positive or negative) represents the amount of linearity in a system.  In NLC, linearity is illusory, gravity can be seen much like the effect of lighting a particular slide.  The slide itself hasn't changed.  One can see this quality of intersecting spirals where spirals overlap at collisions (Figure 2).
In AuT the slide changes in successive, sequentially larger compressed combinations of systems where each combined system changes internally as x increases acording to the broad equation:
F(x)-F(x-1)+F(x-2).  For any F it changes by virtue of being a combination of the prior two F(s) but also each of the two combined F(s) change as x changes.  Otherwise, the internal spirals would  not move.
Put another way:
F(x)-f(x-1) rotated according to the solution for each point solved for x  + F(x-2) roated according to the solution for each point solved for x.
This dual change means that in each system, it's internal components vary as they are combined successively.
