This publication documents a series of ambitious, large-scale projects produced by Christian Moeller within the public sphere between 2004 and 2023. During these years, the artist's practice underwent a considerable shift in focus. Renouncing his former self-designation as "media architect", Moeller began to downplay the role of information technology within his work to instead emphasize its pictorial and sculptural qualities. The works in this volume are based on a keen observation of social processes, often with a view to their playful disruption. At once fitting into and standing out from their surroundings, they present the public with a welcome reprieve from the routines of workaday life. "Open Encounters" offers an exhaustive, lavishly illustrated overview of a highly productive period in Moeller's practice. The book features a career-spanning essay and running commentary on individual works by Jan Tumlir as well as texts by Harriet F. Senie, Cath Brunner, Tim Griffin and Christian Moeller himself.
