I figure if one is going to animate a horse, one might want to understand the mechanics of a horse. And while, yes, it is quite easy to just match up a rigged 3D model to images from a Edweard Muybridge photo sequence, that's not entirely the point of animating, is it? The point, I do believe, is to gain and understanding of how people and animals move and how to recreate that, from any perspective, not just an orthographic side view.
So, hooray for horse studies!
And it's now reached 6am... again. I reaaally have to learn how to do artwork during the daytime.
