The project Interfight (2015) is a series of physical bots, (DataPolluters) that interacts freely through touch-screens accessing to social networks, browsers and webs. These untraceable bots, behaves as intruders: taping, clicking, scrolling randomly, opening and closing applications or taking decisions, in order to provide wrong information for tracking and website analysis. Interfight obfuscates the mechanism of data capture and data analysis in platforms such as Google, Facebook, Amazon, or Aliexpress, being an important ally in the fight against Surveillance Capitalism. This workshop addressed to those who have concerns about critical Interfaces, new media cultural politics and non-conformism towards the Internet data management, especially tracking Web site location and Web site analysis, design homogenization and GUI standards. Practically, this Workshop focuses on basic circuit development, welding and the ensemble of BEAM robotics –a type of stands for Biology, Electronics, Aesthetics, and Mechanics.
