The thermochromic pigment, now irreversibly blended with the tubiscreen medium, engages in a continuous dialogue with the heating elements underneath. Each time the vest is activated by the proximity of a person, the pigment responds to the heat, revealing and then hiding patterns on the vest. Over time, after many cycles of heating and cooling, the pigment will degrade and lose its ability to become invisible, highlighting the ephemeral nature of the gaze and its impact on interpersonal interactions.

+ma (Piuma) is an exploration of the delicate balance between technology and materiality, illustrating how invisible forces—like heat and presence—can leave visible marks over time. This wearable art piece encourages viewers to reflect on the transient nature of interactions and the lasting impact they can have on the world around us.
