We have a short one for you today.
A while back, Delos stumbled upon this little gem. David Guyll of the Points of Light blog seems to try and rewrite the Keep on the Shadowfell (the first adventure to come out for D&D 4E) adventure for different systems to see how he likes it. He even wrote a version for Dungeon World.
I really enjoy the layout and style of crafting adventures the way Dungeon World does, and this adventure is what I consider the epitome of that style. Have a look and try it out.
