" I think their usage of CSS3 transforms to focus on different parts of the video is pretty clever. Watching the video on its own feels rather bland in comparison." It may have been clever, but it absolutely thrashes my cpu. Why didn't they just do the transforms/transitions in whatever they used to record the screencast? Coda2 looks great but using css3 like that will thrash the browser way more than building it out in Flash would have.
