[Taxacom] Herbarium sequence revisited

Interestingly, the architectural design currently taking shape actually splits the collection into a number of vaults - not entirely different to the 'clusters' you propose.
Part of the challenge is to consider how the APGII phylogeny, as expressed in the families represented in the Western Australian flora, and the number of specimens of each family in the collection, might best be assigned across the four equal-sized vaults.

Here is a totally radical thought, that basically just represents thinking
Basic premise: a linear sequence seems antithetical to our tree-like model
of evolution, yet some of us desire that thearrangement of families relate
Would it be at all possible to arrange cabinets not in linear rows, but in
*clusters*??? Islands representing the various APG II orders? And the
allied clusters nmearer one another? It would probably be terribly
wasteful of floor space, but that might depend on the footprint
available. In some spaces, would it perhaps be a more efficient use of
space?? (I have a hard time conceptualizing in 3-D so I can't say.)
In any case, it might be something to consider, for folks who have rejected
the ease and convenience of the alphabet.
