:D that made me laugh:
I don't know if I should say this but that bit you did about gravity off a hill is quite a reversal of a solar system which draws things to the center, rolling off a hierarchy hill is strangely a decentralization affect when things can fall off the hill from all sides, 360 degrees all around, meaning the opposite of a funnel.
Interesting change of perspective is it.
