I just wrapped up a text-only commentary for I, Crimsonstreak where readers can get a look at all the different references throughout the book and what influenced the story.
I'm now experimenting with putting together video commentaries (basically, just reading the text commentary, adding some pictures and effects). I started with Chapter 1, which is one of the longer commentaries. It's clocking in at about six minutes. The author's commentary can work like a podcast...the images aren't all that important and readers could listen while browsing something else on the net. I'm just not sure if it's worth the work to do 17 chapters and five appendices, though.
I'll see how it goes for the first one, which is now A-rolled. It needs a bunch of images and a music track...we'll see what happens.
