Siglio Press recently announced a book called "Between Page And Screen", what they call "a digital pop-up book." Each page will contain no words at all - only a special QR code that the reader can hold up to a webcam, allowing sections of the poem to appear on their screen.
Carlton Books used this technology last year for a series of children's books with augmented reality content.
But for the most part, such technologies have been supplemental to the text itself, whereas "Between Page And Screen"'s physical book contains nothing but black-and-white codes.
If you, like Jonathan Franzen, are skeptical of digital book technology, bear in mind that poetry has always been about different forms of word art and experimentation. As Ralph Waldo Emerson once put it, "All life is an experiment. The more experiments you make the better."

Correction: the text originally contained a mistake in the title of the book. This has since been corrected.
