A library composed of stolen copies of anything ever written by humans and an army of homunculi without language. Take any request, shred it, divide the shreds into little piles based on your personal aesthetics. Send the army sprinting on random paths through the library looking for other little piles that are most commonly associated with their own.
If you don't like the reconstruction, repeat the request, with no guarantee of the same homunculi, or the same paths taken.
