[…] “The primary goal of the model of digital media developed above is not found in its individual components. My main hope is not that readers will come away with an understanding of every nuance of what I mean by data or surface. Rather, my hope is that a basic understanding of these components will provide the foundation for a new approach to thinking about digital media (and computational systems more generally). I use the term operational logics, described further below, to name a new type of thinking can help identify and analyze. When a work of digital media operates, this can be seen as an interplay between the elements of the model discussed so far: data, process, surface, interaction, interplay can be informative. Is the system actually doing what it is described as doing? What unspoken assumptions are built into the ways in which operations proceed?” (Noah Wardrip-Fruing, Expressive Processing.
