Theories and Conspiracies about Relationship Between the Museum Proper and the Mess:
Compare a diagram of warp alignments of the Mess to a diagram of the Museum, it doesn't take too grand a stretch to notice the similarities to the Mess that the Museum has:
There are whisperings that the Museum is not merely derivitive of the Mess, but was an older, stricter, and less-fertile architecture prefering much more deliberate creation than the Mess and its carefree productions.
Was the Museum the failed prototype for the Mess, unable to nuture actual civilizations within its narrow halls?
Is it the 'Jewelbox' of Puzzlebox, a container for keeping the best elements produced by the Mess from being lost?
Could they be lovers, the Museum being the male component to the female Mess, colaborating together in the seeming parthenogenesies in the Mess?
(Or maybe the genders are reversed: Distantly, Kasuri says, "I'd think the way I did because the Mess tends to be, well, a mess. Crap strewn everywhere, no particular order to any of it.

- "A Mother indulges us, lets us explore so as to learn what she can teach us. Her hand is forgiving and guiding. A Father disciplines us, shows us order and makes sure we do not go astray. His hand is firm and directed. Thus, we may run amok in the Mess, and it remains, true to its name, a Mess, but we can see the order and elegance of this discipline in the Museum.
- "At least, that's how it would make the most sense to me right now if we narrowed the field of inquiry thus; I'm truly not sure where the Museum stands. Yet..." --GrayZero
Or is it convergent cosmology, potentially even a rival biding its time?
Alternately, the Museum could be the steamy lovechild of PB and some other equally as bizarre universe. Say, one made up of ...[Jelly].
