What this makes
Glowing neon signs and small props for cyberpunk streets, night markets and arcades. Type a word or two, pick a tube font, an icon and a frame, and the tool draws it as lit glass tubes: a hot white core, a coloured rim and a soft glow around it. Put it on a dark plate, a metal box or a brick wall, add the wires that hold it up, or switch to pixel art to fit a retro game.
Animated signs
Real neon is never quite steady. Flicker makes the tubes buzz now and then, Blink turns the whole sign on and off, Letter chase lights the letters one by one, Broken letter leaves one letter that keeps dying, and Colour cycle shifts the tube colour. With Pro you get the loop as a GIF and as a sprite sheet with a Godot 4 SpriteFrames file, plus the unlit sign for when the power goes out.
City props
A vending machine, a wall air conditioner with a spinning fan, a hologram billboard with your own text, a neon street lamp, a door with a blinking keypad, hanging cables, a trash bin and a hovering drone. Each one is animated and takes your neon colours, so a whole street can match.
Using the glow in a game
The PNG keeps the glow as soft transparency, so the sign lights up whatever is behind it. If your engine has bloom, Pro also gives a glow-only mask you can use as an emission texture. In Godot, an AnimatedSprite2D with the SpriteFrames file and a CanvasItemMaterial set to Add blend makes the glow add light to the scene.
Fonts
Tilt Neon, Monoton, Orbitron, Share Tech Mono and Silkscreen are under the SIL Open Font License, so your signs can go into a commercial game.
