??hmm, so what about something about relationship between [toric maximal atlas of projective space (??and/or of more general grassmanian or partial flag variety ... or something ...) as having interpretation in terms of something about (??overlapping/superimposed??) bruhat classifications and so forth] and [??something about "kaleidoscope as fan" and so forth ...] ?? ... and so forth ...

??maybe level slip here, or something??? something about situations where some partial flag manifold _is_ a toric variety for some (perhaps good ... ??...) reason, vs situations where some sort of toric variety is nicely systematically associated to a partial flag variety ... or something, and so forth ... ???.... ??probably have run into this level slip before ??? ... and so forth ... ??...
