There is one obvious exit: backward.

Clockwork by Westley

This is a large, plain pine shelf. It's perfect to display a large collection of prized items, or some larger heirlooms.
It is in excellent condition.
On the large pine shelf are a clockwork orange, a carriage clock, a little metal castle, a clockwork soldier, a clockwork carriage, a Klatchian Fire Engine and a little metal windmill.

This orange is a very punk version of the fruit, and is definitely something you wouldn't eat. It is orange coloured and round, but looks like it has been assembled by the Unseen University librarian using a very blunt object out of a few bits of metal. It does have two squishy bits on either side that can be used to squirt its contents at people.

This is a small, square brass clock with a plain white face. It's the kind of clock one generally receives upon retirement from people with little imagination. On top of the clock is a small bell that appears to chime the hours.
The clock tells the date as well as the time.
According to the dials it is half past one on Friday the 9th of Ick.

This is a small scale model of the famous Lancre Castle that has been crafted out of metal by what was probably a blind elephant on crack. Even so, it does resemble a castle, with little turrets, a courtyard, high walls, a drawbridge and lots of little soldiers. It would be fun to play games like Sto-Lat invaders with, assuming no one was around to watch you playing with little toys.

This is a rather garishly dressed toy soldier. Wearing a bright red uniform he would have the life expectancy of a chocolate kettle on a real battlefield. A tiny key sticks out of the back of the soldier, looking incredibly turnable.

This is a small clockwork replica of the carriage the Patrician uses to travel around Ankh-Morpork, which explains the arrow proof metal sheeting along the side of it, and the high leather seats that can easily be ducked under in times of need. It has a key sticking out of the top which can be used to wind it up.

The Klatchian Fire Engine is a formidable weapon of war, so bad that it has been banned in eight countries and three religions will excommunicate any members found using it [five more embraced it as a holy weapon]. It is designed to spray flames over anyone standing in front, behind or infact anywhere within a fifty metre radius, including the operator. It consists of a sort of bin on small squeaky wheels, with various handles, fat leathery bags and a nozzle on the front which you could ignite if you were so inclined. The leather is well greased and there appears to be oil in the reservoir.

This is a small windmill that has been less than skilfully crafted out of metal to resemble the windmills found in some rural areas of the Disc. Its tiny leather sails spin slowly in the breeze, and if your lungs haven't been destroyed by breathing Ankh-Morpork air, then you could probably blow on the sails to make them spin fast.
