We asked Gemini 4 Argon to make a realistic 3D scene in pure Python with zero external libraries.
It wrote 5,000+ lines of code and built its own 3D ray-tracing engine, custom video tool, and audio mixer to render and document this sunlit library from scratch — producing, narrating, and assembling this video with Gemini 3.8 TTS and music by Lyria 3.5.
