This is the first of the 2011 one shots from the animator training program. You can read more about the program on the Anime News Network. This one, titled Buta (TL note buta means pig) is about a sword-wielding piece of bacon getting eaten by cats. (Torrent)
We did the 2010 series as well, which you can download on BakaBT. With the exception of Torracman, they’re pretty good.
