A night-time pedestrian crossing signal whose LED stick figures dance, swap lamps, then spell your headline and switch off. Copy the prompt into Claude.
A neon-lit pedestrian signal stands at night. The little LED figures in its three lamps stretch, dance and fall through the housing walls into each other's lamps. They bounce on a trampoline line, swap places, freeze back into regulation poses, then type the headline across the lamps and switch off one by one.
Change the headline (slashes split it over the three lamps), each lamp's LED colour and the two neon rim lights, left and right, by asking Claude. The 25-second vertical format suits TikTok, Reels and Shorts, end-of-day or end-of-week posts, and sign-off sections.
0 to 2.8 s: a normal signal: the tall figure in the regulation stop pose in red, a flat green ground line below. He looks left, right, then stretches on tiptoes and settles with a squash.
2.8 to 6.4 s: three jumping jacks, four disco points, a ta-da.
6.5 s: he hops through his floor: head and arms stay in red, legs kick in the top of the amber lamp.
7.25 s: amber flickers on; the stocky figure wakes, looks up at the feet. At 7.8 s the hands slip, he drops; stocky runs under and catches him into a two-figure tower that wobbles harder each…
9.25 s: stocky's knees give and he is hammered through the floor onto the green line, which stretches like a trampoline. Bounce one pops his head back into amber (peekaboo, the tall one waves down), bounce…
12.6 s: the hat figure walks in along the sagging line and tips his hat.
14.3 to 17.8 s: three seesaw shuffles: landing on one end of the line fires the others up into higher lamps until everyone has moved round and back.
18.1 s: everyone freezes in regulation poses. Nothing happened. At 18.6 s all three wave (the hat gets lifted).
19.6 s: they duck out of their lamps one by one (clipped to their own lamp). From 19.9 to 21.4 s the headline types in, one LED letter per step.
22.67 s: red relays off with a flicker, amber at 23.0, the last lamp flickers and goes at 23.67. Dark housings, neon only.
Light, camera and post
Night, no key light. Build the environment map from emissive cards in a black room: a hot [right neon colour] tube and soft box from right and behind, a [left…
Backdrop: near-black with soft pink and cyan haze, about 34 far bokeh discs, and dust motes drifting through the neon, kept clear of the lamp faces.
Camera: a keyed orbit (smoothed, plus slow sine drift) on a narrow 24 degree lens. It starts 27 degrees off-axis from the front left, drifts to the red/amber seam for…
Post: 4x MSAA half-float render, golden-angle gather depth of field focused on the lamp faces, bloom, slight corner fringe, vignette, cool blacks, ACES, fine grain.
How the prompt opens
Make a silent 25-second, 9:16 (1080x1920, 30 fps) motion piece in Three.js. A photoreal pedestrian crossing signal stands at night, lit only by neon. At the end of the shift the little LED stick figures in its three lamps come alive: they stretch, dance, fall through the housing walls into each other's lamps, bounce on a trampoline line, swap places, freeze back into regulation poses as if nothing happened, then type [your three-part headline, e.g. "Time to / clock / off"] across the lamps and switch off one by one. Swap in your own line and colours.
