# Opus 5.5: A Single-Line Pelican Riding in 3D

An Xuan explicitly credits Opus 5.5 with drawing every frame in JavaScript on a 2D canvas and synthesizing the music in code. The recording progresses from points and a single line to a pelican and bicycle, then lifts, rotates and pedals the construction in 3D. The complete approximately 43-second 1080p, 30 fps original video and AAC stereo track are retained. The 16,384 points, Lloyd relaxation, travelling-salesman tour, 2-opt and zero crossings are creator claims or displayed values, not independently recomputed. Published at 21:46:26 UTC on 14 October (05:46:26 Beijing on 15 October); generation date, full prompt and iterations are unknown. The quoted fofr Fourier work is already archived and is not counted again; this record retains An Xuan’s own 43-second work. Complete JavaScript is not public, so no playable on-site demo is claimed.
