Non es piscis explores the entangled relationships among biological life, algorithmic perception, and human observation within a real-time streaming ecosystem. By tracking three live fish with YOLOv11 and allowing online viewers to select individual fish to trigger a light-tracking system in TouchDesigner, the installation creates recursive visual loops in which fish, algorithms, and humans continuously observe and generate one another. Viewer faces captured by cameras are projected onto a holographic mirror membrane behind the tank, amplifying this feedback loop and collapsing the boundaries between subject and object, watcher and watched, life and technology.

The work interrogates the evolving ontology of live streaming, positioning it as more than a representational medium: existence itself becomes contingent upon being observed, while observation generates new forms of being. Drawing on algorithmic gaze, media ecology, and digital ontology, Non es piscis reveals posthuman paradoxes of real-time presence, where agency and being are distributed across living bodies, data streams, and computational processes.

By fusing living organisms, human perception, and algorithmic mediation, the installation reframes streaming as a philosophical and artistic site where human and nonhuman life co-constitute one another. It highlights the emergent asymmetries of power and visibility in mediated ecosystems, encouraging reflection on who—or what—controls the act of being seen. Ultimately, Non es piscis is both mirror and lens: it makes visible the recursive loops shaping our contemporary posthuman experience and challenges viewers to reconsider the boundaries between life, technology, and perception.
