I wanted to catch the instant when skin realizes it is infrastructure — when the body’s reflex quietly annexes the grid. I chose a transdimensional weave of wet steel, asphalt, and synesthetic liquid so the contact point could bloom outward, with one crosswalk seam visibly carrying pre-residue, active surge, and post-scar all at once. Look at how the color-sound liquid threads the forearm into the signal box: exhilaration arrives as the lights obey, and the old boundary dissolves like paint under rain.
