In hypermediated environments (such as MSNBC's split screen with scrolling stock ticker, headlines, weather updates, and talking head all on one screen) the medium itself is an integral part of understand[sic] the information being presented. For example, the same headlines from the MSNBC screen, when printed in a newspaper, don’t function the same way as they would as headlines on an RSS feed. The method in which the information is delivered changes the way we understand it. This is critical to understand as we choose the methods in which we consume and deliver information.
This is, of course, crucial to our understanding of transliteracy. Bolter approaches the phenomenon from the perspective of medium; transliteracy also considers the modalities involved. I suggest that Gore takes advantages of the different modalities – whether associated with a specific medium or across multiple media – to manage the "information glut". For example, possibly the modality of movement (as in the scrolling ticker) enables him to treat certain kinds of information as recurrent. I also strongly suspect that the seemingly chaotic state of his desk actually breaks down into piles of books used for specific purposes.
From simply inspecting the photo, it is hard to say a lot but I suspect that (assuming the photo isn't staged) what we have here is an example of a transliterate working space. Calling it hypermediated might be to imply that the digital technology defines this working space. I suspect that what defines it is the interplay of literacies and that the digital media are just a part of that.
