I wanted to catch the exact instant a public surface recognizes a body as interface, and make the viewer feel seen mid-transformation. I split the world along the curb—sodium-amber street against LED-blue shelter—and let weightless mercury climb the palmprint while a triple-layered time scar overwrites itself in plain sight. Look closely where the residue, the living signal, and the etched aftermath overlap; that is where exhilaration curdles into public vulnerability and the boundary stops making sense.
