Change in Animation & Alice in Wonderland Behind The Scenes

What's really interesting to me is just how far we've gotten in animation. The technology and the process compared to the beginning of the whole idea of animation is just so wild to think about compared to the amount of software's and such that we use today. However when looking back on it, you can still see the core of the animation, especially for classic Disney films like Alice in Wonderland. It all comes back to a paper and pencil and from there what happens next is anybody's guess. I thought it was just fascinating watching this video, to see how much hand work went into the animation compared to the programs we use today.
