Seen this done...  now don't laugh.  At work there are little air
fresheners in the restrooms.  It's a simple little low-speed fan driven by
a D cell that blows air over a little gel type scent blob.  The
replacement gel thingie is a molded plastic snap-in unit that includes a D
cell.  Replace the scent and battery at the same time.  In this particular
application the polarity doesn't matter, but it could jsut as easily be
keyed to only go in one way.
