Pathfinder Flip-Mat: "Arcane Library" [RPG]

The Arcane Library flip-mat is really nicely designed.  The front side cleverly uses multiple levels of elevation to create a really interesting space for encounters (and it's clear where stairs start and stop and how the levels related to one another, which isn't true for all flip-mats!).  There's plenty of bookshelves (obviously, a must!), but also worktables, statues, and a large orrery in the center.  I use this side of the mat to represent Mad Multivar's house in my Roots of Golarion campaign and it's worked well.  This side of the mat doesn't even need to be an "arcane" library, and could function perfectly well as a normal public library--though perhaps a bit of a messy one, with some books scattered on the floor here and there.  The other side of the mat is one I've only ever used in PFS as it contains "magically separated practice and experimental spaces"--essentially, a collection of rooms separated by what looks like walls of fog.  I'm dubious.  One great side and one okay side still add up to a pretty good flip-mat overall though.  The usual advantages of Paizo flip-mats (folds easily, clear gridlines, wet and dry erase, etc.) are here as well.
