so is the (??) fan of a toric variety something like a saturated / maximal atlas ???....

??talking about toric varieties with todd recently... bringing back memories of ideas from, for example, around december of 2008 (i think ... hopefully can find some of this in various notes from around then ...) ... ??something about toposes and so forth here... also something about ... "double interpretation ... " ... ??how did that go ?? ... ???something about stacks or something ??? .... ???.....

??something about .... ???kaleidoscope as fan, and so forth ... ????.....

??maybe the main (?...) "double interpretation" that i was trying to remember here is... ??something about ... "toric points" ... vs some sort of "orbit stack" ..... ??? .... ... ????or something ????.....
