I was gonna say Bakemonogatari, but since that's your answer, I'll put my second, Madoka Magica. I can't even describe how beautiful the animation in either of these shows look. I'm going to post an AMV rather than a picture, as I think it shows the impact of Madoka Magica's animation a heck of a lot better. Oh my god, just watching clips sends chills down my spine... Ack I'm freaking out!!!!
Death Note. I've read the whole manga (I own all the books in special edition :D) and the "How to Read" book (which includes the author's and artist's thoughts) multiple times, but I still can't take my mind off of the amazing art.
