Why a hexagonal grid. If we have several overlaying grids of different orientation and scale how do they know which grids to activate?
If the mechanism is bottom up, we are at point A and point A has an overlap with the active part of grid X and likewise for several grids. This is backwards the specific to a large unspecific grid how can that help? It makes more sense to have some top down global signal to trigger grids but how could this work?
