Neon circuit sign logo

Neon sign logo animation: current races along circuit traces and draws your mark as a glowing sign. Copy the prompt into Claude and add your brand name.

A cyan pulse charges a chip pin on a wet black circuit board, then races along copper traces, sparking at each junction, and draws an omega. The mark peels up like a pop-up page and becomes a glass neon sign standing in its reflection. Current runs beneath it and the brand name drops into place.

You can change the brand name (up to ten characters), the current and neon tube colour, the wordmark colour and the haze glow behind the sign. At eight seconds and 9:16, it works as a logo sting for tech and electronics brands, intros for Reels and Shorts, or a stream or podcast sign-off.

Specs

What happens, beat by beat

  1. 0.00 to 0.42 s, anticipation. Macro, shallow focus, low along a chip's pin row. Only the centre pin charges: a cyan glow swells and stutters, and tiny jagged arcs hop to its neighbours. The camera creeps…
  2. 0.42 s, release. Pin flash and spark burst. The pulse snaps out with a launch kick (about 1.6x speed, decaying in 0.09 s), then cruises.
  3. 0.45 to 1.45 s, the race. The head runs away from the lens, splitting at each junction. Every junction and dead-end via fires sparks, a ring of current racing across the printed grid, and a point…
  4. 1.45 to 2.62 s, drawing the mark. Two heads run into the omega's feet and climb its sides, slowing to a third of their speed. A glass tube grows behind each head; the copper under it…
  5. 2.62 s, the meet. Two or three frames of white overexposure, 110 sparks arcing high, a thin shockwave ring racing to the frame edges, a 4-frame camera kick.
  6. 2.80 to 4.05 s, the lift. The omega, hinged at its feet, swings up 90 degrees, overshoots about 4 degrees and settles, leaving a glowing copper groove in the board. Sparks kick off both feet as…
  7. 3.02 s to landing, ignition. The neon strikes in 7 zones on two continuous tubes, alternating left and right from the feet upward. Each zone stutters through a few hard on/off strikes before it catches; the…
  8. 4.82 to 5.45 s, the line. Current runs from the foot electrodes out to the line ends (bright caps, a spark puff); a centre run joins the knees, so one continuous line spans the wordmark.
  9. 5.02 to 5.9 s, the wordmark. Letters drop out of the line centre-out, 0.13 s apart, at final scale (only height, depth and opacity animate). Each holds cyan-hot for about 4 frames, then cools to white…
  10. 4.6 to 8.0 s, the hold. A slow 9% push with a 2 degree orbit. At 6.8 s a white-hot packet runs in from the line ends and up both sides to the top, lighting the…

How the prompt opens

Make a silent 8-second, 9:16 (1080x1920), 30 fps logo sting in Three.js. A pulse of cyan current leaves a chip on a wet black circuit board, races along copper traces, splits and sparks at every junction, and draws a stylised omega. The omega peels up off the board like a pop-up page and becomes a real glass neon sign standing in its own reflection. Current runs out along a line beneath it and [your brand name, up to 10 characters, e.g. an electronics brand called OHMLINE] drops into place under the line. Swap in your own name, mark and colours.
