The original Pixar characters were also CalArts style; in fact they were more CalArts than the modern "beansmile" characters. The "A113" easter egg in many Pixar movies refers to a classroom at CalArts. "CalArts style" was a slur coined by John Kricfalusi for animation from the likes of Disney and Don Bluth from the 1970s-1980s or so, with its emphasis on details and stylized realism, which he loathed. (John Kricfalusi loathes any animation not in the style of Bob Clampett, and I think he also loathes women older than 18 years old...)
Later, chuds picked up on this term and used it to refer to "any animation I don't like" which is where we are today. Let's stop using CalArts as a slur. The institute produced and continues to produce very fine animators.
