Animator/director Nick Cross (The Waif of Persephone, Yellow Cake) outlines his animation process, with lots of little video clips showing things as they progress. He's animating a new film called The Pig Farmer. A great, great blog post- especially for you guys who've never animated in 2d before. Those previous students of mine who adhere to the more 2d-centric way of animating in CG will find a lot of very familiar thinking and approaches.
Be sure to check out his other posts, he has one on his inking process in Flash, too.
