Too awesome - if it wasn't late and a Tuesday night I'd be stuck into this already.

The video download links do seem to be dead. Any chance you could fix this or upload to Vimeo/Youtube?

EDIT: for anyone wanting to download the videos, open the "network" panel in Chrome. As you press play, a working link for the MP4 will appear - you can visit this link to download. I would recommend downloading these and playing them in slow motion (e.g. using VLC) as it makes them much easier to follow.
