A full voxel engine that Matt Shumer says Fable 5.2 built from a single prompt. It runs live in the browser, and the sound is part of the experience: he tells people to turn it on. The demo video shows a blocky 3D world you can explore in real time, with the kind of lighting, terrain and audio work that normally takes a team weeks to wire up. The surprise is that one prompt produced the renderer, the world and the soundscape together. It pulled 733 likes and over 250k views on X, and people called it mind-melting. Credit to @mattshumer_.
