I'm also experimenting with very basic hand-drawn animation lately. I've put a few hours into a small project and I'll keep you posted on that soon. Anyone who has quick methods (I hear Flipbook is a good program), tips or techniques to pass along, feel free to email me or comment here. I really respect animators, and it's not easy.
Lastly, I'll be finishing up some Digital Podcast videos this week to post at the Digital Podcast Blog. I know I've teased and stalled on this in the past, but I really do have time this week to finish it up, and I'll let you know when it's here.
