Aug. 24, 2025 — Elon Musk has shared an rokinteractive 3D visualizer, which moves and changes shape in perfect time with live music and sounds.
Built using the popular web graphics library Three.js, the demo shows how artificial intelligence and creative coding can work together to produce vivid, browser‑based art that reacts instantly to audio.
In the short clip, geometric patterns swirl, pulse, and glow in sync with the beat, creating a hypnotic light show entirely inside a web browser.
The system uses real‑time audio reactivity, meaning the visuals respond immediately to any change in sound, from deep bass drops to sharp treble notes.
According to the creator, the project combines WebGL rendering through Three.js with Grok 4’s AI processing.
The AI interprets audio frequency data and turns it into animation commands, which then transform the shapes, colors, and movement patterns on screen. No special hardware is needed — just a standard computer or phone and a modern browser.

Musk’s retweet has quickly boosted the video’s reach, sparking conversations about how AI could be used in live performances, art installations, and even educational settings.
Many viewers see it as proof that advanced AI models like Grok 4 aren’t limited to text and chat — they can also create immersive, real‑time visual experiences.
The demo’s simplicity — running entirely in a browser — could make such experiences accessible to artists and audiences worldwide.
As more developers explore Grok 4’s multimedia potential, we may soon see AI‑powered visuals becoming a standard part of digital creativity.
