Hilarity will

Seriously. My entire trade depot once exploded because somehow a trader brought a bag of

Now you can have them engrave things like "the spear is impaled on the goblin" (instead of the boring "the goblin is impaled on the spear") or "the elf is hugging the one thousand four hundred fifty-nine trees" or even go way overboard - to the point of Planepacked levels (that famous thing that was due to a bug) if not beyond that!
Oh, and the game's a freeware one.
