To explore how interfacing shapes spectatorship online, Vendela Grundell examines experiences of the flow of digital culture through the friction of photo-based glitch art by Philip Stearns, Rosa Menkman, and Evan Meaney. With a focus on the viewer, these three cross-disciplinary case studies analyse material new to the art historical context. In particular, they focus on how glitched artworks in online environments can make viewers aware of their own activity within the flow, causing a break in the increasingly naturalised integration of system and individual. A tactical potential emerges when a glitch invites the viewer to try out different positions relative to the system.
