Kino's Journey
Haibane Renmai
Elfen Lied
Paranoia Agent
Technolyze
Definitely not enough people have seen those anime's, despite being among my all time favourites. In fact I've never met another person who's seen Kino's Journey or Technolyze. Most people can't seem to get over the fact that Technolyze has nearly no dialogue for the first 5 episodes, and Kino rides a talking motorcycle. Eh, more's the pity for them.
