# Gemini 4 Argon · 3D pelican cycling with Fourier epicycles

fofr’s Fourier epicycle animation progressively reconstructs a cycling pelican from rotating circles, animates pedalling, then rotates the view to reveal the 3D construction. The original post credits Argon with making the video and prompting time-synced Lyria 3.5 music; model and process labels are source-reported and unverified. The complete approximately 60-second, 1920×1080, 60 fps original video and audio are preserved without cropping, redrawing or added motion. Published at 2026-10-13 16:20:34 UTC (14 October at 00:20:34 in Beijing); the artwork date uses the original post’s UTC publication day, and generation date is unknown. The author’s reply links a generic starting prompt for a slow Fourier reveal styled after a reference image with synchronized music. The exact pelican prompt, reference image and source code are not fully public. Displayed N, node counts and error values are part of the original presentation, not independently verified scores or generation counts. No playable on-site demo is claimed.
