I've been meaning to watch that one.
Right now I'm in the middle of Texhnolyze (fucking awesome) and Welcome to the NHK, re-watching Simoun (quite possibly the only yuri show that has a proper explanation for why it is yuri), testing a bunch of others, like Minami-ke, Today in class 5-2, downloading and possibly re-watching Hitohira (yet another school/slice of life/comedy show... still damn funny, and fun).
I'm thinking of checking out Xam'd, Kurenai, Chaos; Head, Kurozuka, Koi Kaze, Kaiba, Le Portrait de Petite Cossette, Otogi Zoshi, Noir, Planetes, and god knows what else.... (list here more to remind myself, than anything)
