Oh I saw that in my History of Animation class in college. Very cool shit. Today everything is so standardized, everyone does everything with CG. People love the crap out of Pixar/Dreamworks but the animation and art style is funneling all animated features into an artless, profiteering creative wasteland. Back in the day people would get really and truly creative with their animation methods. It was so much more REAL, so much more inspiring. I mean come on, how innovative is it to animate something with 3D Max versus experimentation with acrylics on glass.
It used to be a true artform to be able to produce an animated feature, with thousands of hours of tireless carefully-metered paintings on various mediums. Now it's just an assembly line, an inspiration to true mass production. Which makes me sad
