The work “Membrane Bodies” constitutes a living ecosystem of relations. It is a hybrid installation that is structured as an active biotope. A field in which life is not represented, but is experienced and continuously transformed. The approach begins with the active capacity of matter, according to which matter is not treated as a passive medium, but as an active participant that co-shapes the processes and relations within the system. The central element of the biotope consists of organic membranes made from algae and natural biopolymer materials. The membranes constitute a “body,” in both a metaphorical and functional translation of the body. They adopt the properties of skin: they are fragile and bear traces of wear and trauma. Their corporeality is not embodied through form, but through their behavior. In this sense, skin emerges as an intermediate space between the “outside” and the “inside.” The work is activated through care-based interactions such as humidity, dehydration, and touch. The membranes are reconfigured within the space as their outer layer begins to “move” inward, generating asymmetrical surfaces. The action does not “belong” to any of these elements individually, but is determined by the arrangement of matter at each moment.
