I'll check it out soon and tell you what I thought about it. You really should see Scryed.
Haibane Renmei
Planetes
Aachi wa Ssipak
Needless
Scryed
Dead Leaves
Now and Then Here and There
Level E
Desert Punk
Those are a couple of recommendations. I really liked all of them and they're reasonably unknown. If you haven't seen Planetes, Haibane Renmei or Now and Then, Here and There I highly recommend that you watch them.
