Sophie Warren and Jonathan Mosley with Can Altay’s ‘Rogue Game Replay’ was commissioned as a solo show by Casco, Utrecht. The show within the gallery space of Casco was accompanied by an event ‘Rogue Game, First Play’ that took place in the Olympos Sports Hall in Utrecht. The exhibition overlaid the logics and systems of the multi-use sports hall onto the gallery space and overlaid the sports hall and gallery onto the office of the Casco organisation. Within this exhibition setting the superimposed territories, rules and functions of each layer were negotiated by office workers and visitors through moments of contingency, play and collision to define a new gaming arena and strategies for co-habitation. Documentation of the event ‘Rogue Game, First Play’ infiltrated the office computers as a screensaver. The moving image work ‘Waiting (screensaver)’ shows a moment before the start of a game, of players waiting in anticipation of play. The footage is looped and uploaded as a screensaver that intermittently interrupts office work when office computers are ‘waiting’ and not in active use.
