I can vouch for gits, habane renmei and tatami galaxy.
I think you can skip innocence though, and make sure you get the original gits, not the one with the crappy cgi do-over scenes.
Check out some satoshi kon (perfect blue, paranoia agent, paprika)
Colorful is good too (the comedy skits show or the drama movie)
People have mixed reactions over Ergo Proxy, I think it definitely has some good parts to it.
Belladonna of Sadness is beautiful too.
