It would be interesting add "windows" to rooms and
actually have it query the status of another room when
you look through it. So say you were standing outside
a candleshop, much like doors, you'd have an inside
and an outside general description and if you were
to "look in" or "look through", you would get a more
detailed description.
i.e. Standing outside a warriors' guild where the
guildmaster and 2 PCs are inside. You look through
the window and get a description like: "You look
through the window into the warrior's guild. Inside
you see the guildmaster Harrold, Jared the warrior and
Francis the mage."
likewise, if you were inside the guild looking
out: "You look through the window and see the Market
Square. Outside is Peter the peeping tom."
