This presentation argues that the digitization, proliferation, and mobility of contemporary screens has transformed what was once a "screen-scape" to an all-encompassing "screen-sphere"—a new topologically-bounded, systemically-organized, and n-dimensional domain that has not only radically changed our lifeworld but also our ontological existence, behavior, and spatiotemporal orientation within it. My argument proceeds in three parts that correspond to the three stages of phenomenological method: description, reduction (or thematization), and interpretation. The first, "A 'Cartoon' Phenomenology: Experiencing Screens, or Being (Differently) in the World" draws (quite literally) on recent cartoons and other popular and scholarly discourses about our existential engagements with the screens that surround us. The second, "A 'Machinic' Phenomenology: Screens and the Emergence of a Complex System," explores the observable relations among screens as constituting an "autonomous" or "autopoietic" system. Finally, "Phenomenological Biotechnics: Where and What are We Now?, or Living With/In the Screen-Sphere" speculates on the spatial structure of the "screen-sphere" and its effects on our position and function in relation to it.
