Eoin Colfer's "
Artemis Fowl" series is something i would gladly see animated. (There is a
Movie planned though, but seems like it will cover only two of the books, and will feature an original ending.. )
It is one of my favorite book series, and the theme is something i immensely enjoy. This cross-race information warfare (sort of) and a battle of wits is something which is pretty much my cup of tea. Seeing Artemis in action would be a sight to behold
I think he reminds me of Light (Death Note) in a way... only smarter.
Other than that...
Planetarian ~The Reverie of a Little Planet~ ,a visual novel by Key, is also something i would die to see animated. Though i think it would be a movie in the case... i am not sure whether it can manage a full season without feeling dragged out (After all, the cast is only 2 people). But i know for sure i would be drooling all over the Keyboard, regardless of it being a Movie/OVA/anything.
