I Built a Live Wallpaper Engine for macOS — Here's How It Works

Your desktop wallpaper is a static image. It has been since the day you set it up. Mine was too. Then I thought: what if I could write a React component and have it run as my actual desktop wallpaper? An audio visualizer that reacts to music. A system monitor showing real-time CPU usage. All built with the same tools I use every day. So I built it. Meet Fluxlay — a live wallpaper platform for macOS. Write a React component, and it becomes your desktop wallpaper. I built the desktop app, CLI, SDK, and a gallery (marketplace) for sharing wallpapers. Show me the code Here's an audio visualizer wallpaper. The entire thing: import { useAudio } from "@fluxlay/react"; export default function AudioVisualizer() { const { spectrum } = useAudio(); return ( <div className="visualizer"> {spectrum.map((value, i) => ( <div key={i} className="bar" style={{ height: `${value * 100}%` }} /> ))} </div> ); } That's it. This reacts to whatever music is playing on your Mac. In real time.
