DOT/O is an interactive installation as social experiment / game exploring the capacity and interest of a crowd to ‘complete’ a suggested structure. The project is inspired by ‘connect the dots’, in which numbered dots allow a player to discover a hidden drawing by following the correct order. For the purpose of the installation, the team developed a steel structure to act as host for a crowd-sourced threading experience. Users are invited to pick one of the wall-mounted spools of thread, and connect the dots discovering the 3D surfaces that exist between the different frames. The project was intended to slowly build density, and use color to map the progress of time and interaction through the structure. Simple rules like maximum distances were suggested but not enforced, allowing players to follow or ignore them, resulting in a combination of order and disorder. The stochastic nature of the installation challenges the idea of formal preconceived output, embracing the uncertainty of the social interaction. Slowly, though, the piece would accumulate enough threads where independent intentions would become less visible as an increasingly denser fabric would become the dominant collective creation. The final result, viewed as a social experiment, embraces the messiness of the initial experiment, speculating in the formats and mechanics of crowdsourcing for design. In this regard, we identified that the piece presents a model of cooperative crowdsourcing, not competitive; while many crowd-sourced projects seek to optimize a solution by finding a particular individual that can provide the best answer, DOT/O invites all players to be part of the experience and share the same output.
