The new show to this season :
Recorder and RandsellA quirky show about a brother and sister with an unusual twist. The brother looks to be an adult, while the sister looks to be a total loli. Yet, the brother is a fifth-grader, and the sister is a second year high-schooler. It's quite the interesting take on things~ Too bad it's only 3 minutes long, but Morita san was short, and yet managed to give heaps of enjoyment. The first episode did just that, and left me with a smile on my face
Next up,
Last season's winner :
Morita-san wa MukuchiA show about a girl named Morita who has a problem. She can't manage to converse with words (mainly due to her being indecisive about what to say xD), and this tends to bring in a heap of misunderstandings. Watch as her friends and peers attempt to help her to be more sociable. The cast is quite good, and I loved the whole series ~
Then we have,
The delightful and very colorful :
CopihanIt's random, fun, and very colorful. Though, there's that one episode which manages to be slightly creepy

And then there was,
honto ni atta reibai-senseiBasically it's about a teacher who deals with spirits, and how she messes with the class. Got quite a few laughs outta myself. She also likes cats especially, and there are these talking cats as well. It's pretty random, but works well in short bursts. Which makes sense, considering the length of the episodes
And then the super adorable,
PoyopoyoSeemingly too cute for many, this will be a comedy for all ages and types! Follow this unique family and its spherical cat, in a warm-hearted comedy for the winter!
For a change of pace quite the weird show,
Thermae RomaeIn 128 AD, Lucius is a bathhouse architect in the Ancient Roman Empire. When he loses his job, a friend takes him to a bath to relax. There, he is transported to a bathhouse present-day Japan.
And then there's (taken from myskaros' posts),
Double-JFrom wikipedia:
In a school where after school activities are mandatory among all students, Hajime and her friend Sayo come across a new club that they have never seen before. The club is called "The Cultural Activity Preservation Club". The two enter the room to find all kinds of analog jobs and activities, such as handcrafting mats and toothpicks.
Pretty cute, totally random.
Err, this might count more as a web-anime, same with Nyaru-ani: Remember My Mr. Lovecraft.
Each episode going at 4 minutes.(Edit by Vampko)
Haiyore! Nyaruko-san
2 seasons of web anime, soon to be followed by an
actual full-fledged anime. First season (Haiyoru! Nyaruani) was ~2 minutes per episode, the second season (Haiyoru! Nyaruani: Remember My Mr. Lovecraft) was ~4 minutes per episode. Both seasons deal more with random situations involving the main characters rather than following the light novel plot.
The main characters are Nyaruko (short for Nyarlathotep), a Cthulhu alien who assumes the form of a silver-haired girl, and Mahiro, a human boy who takes care of her after being saved from aliens by her.

Got a great cast who I hope will reprise their roles for the anime. Just from the character interactions in the ONAs, I'm super excited about the anime.
