Get A horse!

Something that I learned from this article is that nobody has ever made an animation in present day that gave the audience a feeling that it was made in the past until Disney made "Get a Horse". Another Thing I learned from this article is that furniture makers beat furniture with chains to give it an antique look? that's, strange.... Stop abusing furniture. I also learned that the animators of "Get A Horse" deliberately inserted mistakes into frames of the animation to give it an Authentic "Antique" feeling. A thing I liked about this article is that it was about a new disney short that they're going to try something new in, Like what they did with the "Paperman" short last year with the cross 2d/3d animation. Another thing I liked was that the article included pictures to give you an idea of what they're doing in the animation . A question that I have about the article is, has disney been doing crazy, never before done stuff in all their animated shorts for a while? or has it just been the last two?
