One-Tailed proposes a gentle act of anarchy, meant to disrupt online tracking procedures. The installation is designed to beat the ‘opponent’ at their own game, perverting its mechanisms and methods. In fact, the movements of a fish in its tank are traced by a camera (1) and converted into cursor actions onto the screen (4). These movements can be misinterpreted as human screen actions, thus creating fake statistics that will be analysed by the web operator (5). The fish is browsing through a series of specific websites from a specially compiled database (6), containing a list of websites that track the fish at the same time as it navigates the website. The absurdity of this analogy tends to expose the idiotic over-use of counting and of data driven decision processes. This protest can perhaps be referred to as a form of stat-activism: misusing statistics in a critical tool that will drive users to question their online agency.
