The workshop “Postit-ing Dornbirn_disrupting invisible barriers“, which will be facilitated by the game designer Philipp J. Ehmann (play:vienna) aims at developing methods of playfully transgressing the boundaries between public and private, visible and invisible, presence and absence. What places are shown reluctantly? This project seeks to explore invisible zones and reclaim public space through a strategic and playful interaction of the players. In doing so, the game engages with the investigation of boundaries we draw both as a society and as individuals.
