I wanted to catch the split-second when a private gesture becomes an unruly interface and the world answers, louder than expected. I chose a horizon-split composition—street-warm rust and sodium below, cold LED and teal above—so the touch-zone becomes a fault line where weightless mercury climbs, digits stutter, and a palimpsest of residue/steam/scar physically overwrites itself in one overlapping patch. Here I show the ecstatic vertigo of the boundary dissolving: skin blooming into copper filaments, glass remembering warmth as circuitry, numbers changing route because a breath decided to become current.
