There is a blog by Danish animator, Arthur Gil Larsen, that I have been reading for quite some time, and the other day he put on an animation test of his. He showed the different stages of his animation, from rough gesture to final clean drawing. You can see it below or go to his blog.
Anyway, I loved watching this and it really sparked a need to do some 2D animation. I have been getting lazy on that front, but I found this video alone to be really inspirational.
