OUR NOTEA demoscene-style intro with a sunlit mountain peak rising above a sea of clouds; left undirected, the model spent about 5 hours and 697M tokens to fit every pixel and sound into one 280 KB HTML file.
I asked Claude Opus 5.5 to make the most impressive demo of itself and gave it zero direction.
~5 hours and 697M tokens later, it made this demoscene intro. Every pixel and every sound comes from one 280 KB HTML file. No images, audio files, 3D models, or libraries.
Sound on.
