A new model with varying altitude of cities / cone tips

[ghost]

Dear shriveling_world team and friends,
I find the time-space compression maps really intriguing, but one thing I always asked myself is: why are all cone-tops (i.e. 'entry points' to the discontinuous transport system) at the same height? Aren't some points/cities more important than others? If a peak in the "spiky world" stands for highest accessibility, wouldn't it be possible (and desirable) to combine the shriveling-world layout with, say, a gravitational accessibility model, in the sense that the 'mass' of a region (e.g. population) also determines the height of a cone?
Best regards,
Fabian Wenner
