So, you want to become a walking anime "Encyclopædia Pretencia"? I guess I can help with that.

Some recommendations:

-Noein
-Sayonara Zetsubou Sensei
-Evangelion
-Zegapain
-Saikano
-Akira (and anything else by Katsuhiro Otomo)
-Anything by Studio 4°C
-FLCL (and some of Gainax's other works)
-Anything subbed/ripped by the group "Jolly Roger" (http://www.btmon.com/Video/Unsorted/JR_Releases.torrent.html)
-Shakugan no Shana, maybe
-Gankutsuou, maybe (only saw a few eps, so I dunno)
-Monster, maybe
-Karas (haven't seen any, this is just a guess)
-Samurai Champloo, maybe (as well as other Shinichiro Watanabe stuff)
-Wolf's Rain, dunno
-Hellsing?
-RahXephon?
-other Satoshi Kon works
-Elfen Lied
-Noir
