# Opus 5.5 · From cycling to a pelican's day

The author extends a high-fidelity cycling-pelican scene into a day at the beach, reporting Opus 5.5, several prompt refinements and roughly 7,000 Python lines. The public recording shows a procedurally generated 3D scene; the model, workflow and code size are author-reported, not independently authenticated. The archived original video track is silent; the source also has audio. No code or explicit mirroring license was found, and this is not classified as playable. The website uses Reddit’s original 720p track; the 1080p track is also retained locally.
