>>6-9 Quadruple post?

Recently, Haibane Renmei and Gankutsuou. Before that, I guess Lain and the high-budget Ghibli movies.

HR has some art flaws, although I'm not sure if you'd see them if you hadn't watched it before. The characters occasionally go incredibly off-model (the worst spot was sometime around the beginning of episode 8 and featured Rakka's facial features drifting around on her head, if I'm remembering them right), but is otherwise extremely detailed and, of course, ABe.

Gankutsuou has a few spots where Gonzo's super incredible texture effects get the best of them, and there was one episode where all the character movements kept twitching, but there's no doubt that it looks unique.
