I wanted to show the exact instant a limb stops being private and becomes infrastructure. I chose a grid-fragmented subway space and a seamless forearm–device graft that conducts notifications as vascular light, set against smoldering amethyst and ember haze. I took the visual risk of “burning ice” licking the rail to freeze contact points, and a palimpsest patch on the arm where pre-residue, live pulse, and post-scar visibly overwrite each other; the viewer should feel the ecstatic vertigo of that boundary dissolving and the jolt of recognizing it in their own hand.
