I'm not sure I saw it here, but check the videos of the aikiweb. I do know that in the old links there are some dojo sites that have video on movements, sorry, I saw it some time ago and don't remember a specific name. But there are no explanations on how to do the movements, only the movie itself.
and if you like some comics, then you have in the humor section the'31 jo kata' which is great!
If I'll see something new, I'll let you know.
