Not only do Bat Country Entertainment have the best name, they have also made the best Minecraft mod. It's a Minecraftian version of console-toy tidying-up-everything game, Katamari. (Yes, I do tidy up by rolling everything into a big ball and throwing it into space, thankyouverymuch.) It's totally playable, with its own HUD, score system, and so forth.
Watch a video of it in action, below. (Via the excellent GSW.)
