Forum:Anime's art styles

Mmkay, so I'm sure I'm not the only person to have noticed that the Inuyasha anime has something like a dozen totally different and awesome (though some certainly less so). I gotta say though, my absolute FAVORITE has to be either the style most easily seen in episode 140 "Eternal Love: The Naginata of Kenkon" (or part of episode 122 works as well), or the style we see a lot more often (episode 58, "Fateful Night in Togenkyo Part II" is what comes to mind first).

I don't think I've really seen so many different artistic styles in a single anime. Anybody know why there's so many? Anyone know who created or was in charge of all the styles?

ALSO WHAT'S YOUR FAVORITE STYLE AS WELL, THAT WAS THE POINT OF THIS XD
