iBook Author app, I'm putting together the iBookstore multimedia interactive ebook, Podcasting for Writers and Other Creative Entrepreneurs... this one will be an iBook ebook edition only, but some of my other works are -- and will-- be available in multiple editions across multiple platforms.
From Mexico to Miramar or, Across the Lake of Oblivion, is a long form essay of creative nonfiction that originally appeared in The Massachusetts Review. Then a double CD. Then a Kindle. Then an iBook edition. And the iBook edition includes video, color, more design, etc,-- thanks to the iBook Author app, it is a substantially richer edition than the Kindle. (But let's see what the Kindle is up to next.)
P.S. Writer and designer Craig Mod has this to say-- and show-- about Art Space Tokyo and platforming books. Viva the future, here now.
