Phallaina is “the first scrolling graphic novel,” and it is fun. Instead of turning pages, you just scroll from left to right. Breaking free of the confines of the codex means there is no need to divide the illustrations into panels. Take a look at this example, where one plane serves first as the floor but then also as a door perpendicular to that same floor:
There are dozens of thoughtful, playful moments like that, all enabled by the scroll.
This is the sort of thing that is both exciting and difficult to think about in relation to a future generation of ebooks. Sometimes, as you can in most ebook readers now, you want to give people the option to switch between pagination and scrolling. But sometimes, as evidenced by Phallaina, scrolling is essential to the experience. Other times text and illustrations will have been carefully crafted to sit together within the rectangle of a page, and in that case not only must you force pagination, you can’t allow the text to reflow for different screen sizes. How do you accommodate all those variables—scroll vs. page, optional vs. forced, formless vs. definite? One of the under-appreciated virtues of paper is the number of decisions that are made for you.
