gabrielchua · x · 2026-09-17

Designer MengTo showcased GPT-6 Astra for motion design: using PerspectiveUI from his ThreeUI library, he had the model generate a Codex promo animation, then refined it through iterations — a midnight-blue nebula, stars forming a 6, progressive blur, 3D camera moves, close-ups of typing, and text particles. The final cut is 30 seconds across six distinct scenes, produced with just three prompts, and shipped as an interactive Three.js web page.
