Antidatamining is a series of visualisations of financial data. Economy is represented by its main agents –companies, groups and holdings, stock exchanges, banks and investment funds– and their interaction: capital relationships, geographic deployments, market structures. Antidatamining is a permanent monitoring device, which aims to highlight the structure of the contemporary economy, seen as a complex dynamic system. The RYBN collective has undertaken a data mining based research project, since 2006. Diverted from their original goals, data mining tools and digital monitoring technologies are used to create a series of images of our society pictured through its data flows. The resulting digital visualisations are updated in real time
