Opus 5.5 builds its own launch video in pure JavaScript

In a single HTML file with no images, fonts or audio, Opus 5.5 drew the sea, planet, title and soundtrack frame by frame in JavaScript, plus a self-referential easter egg at 20 seconds.

This was a one shot! I asked Claude Opus 5.5 to make a launch video for itself. It built everything out of just text. The sea, the planet, the title. Every frame is characters drawn in pure JavaScript! Even the soundtrack! One HTML file. No images, no video, no fonts, no audio files. All pure Javascript! Insanely impressed! The attention to detail is on another level! It even added its an easter egg all on its own! at the 20s mark the code seen on screen is part of the actual code it wrote to generate this exact video! Skill.md attached bellow. Try it yourself!
