A demo credited to Opus 5 shows a procedural painterly world with wind-reactive grass, packed into a single HTML file.
The shared CodePen renders a stylized landscape with soft lighting, rolling terrain, and animated grass that responds to wind. It is the kind of tiny, self-contained visual demo that tends to travel well in AI circles because it looks unexpectedly polished for how little code it appears to need.
