If you use MongoDB and you haven't heard of Genghis, you may want to check it out. It might not be very long before Genghis conquers most of the MongoDB installations in the world. It's simply described as a single-file MongoDB admin app and then it goes on to describe itself solely by using pictures. It's an interesting method.
I guess the name "Genghis" was probably inspired by MongoDB's similarity to the word "Mongol". But that's just a guess.
