This chapter addresses the pervasiveness of computer screens by following a phenomenological conception of screens as mattering only as screens-in-the-world. In this first section, the term “screenness” is introduced to describe how artifact, enactment and contexts of actions need to be dealt with in a holistic manner. Following this, the specific characteristics of the computer screen, interweaving basic principles of computing and cultural impact, are discussed as grounds for further consideration. This discussion and the phenomenological conception of screens provide the basis for experimenting with screenness through art-based research. The chapter closes by summing up findings from the experiments. Furthermore, the question of the shaping of knowledge through the suggested methodological reframing is discussed.
