Editable motion recreation built with Astra, JavaScript, Canvas and WebGL.

Reference / challenge: https://x.com/jordanarchivess/status/2107536262894915762

Run

Clone the repository, run npm ci, then npm run setup and npm start.

The setup command downloads and SHA-256 verifies the ten texture archives below, extracts them, and removes the temporary archives. Total texture data is about 8.6 GB; the archives stay out of Git history. Each part can be resumed independently.

motion-recreation-demo.mp4 is the compact 1080p playback version of checkpoint 11. The published code includes later refinements; no new complete-film similarity result is claimed. The last complete audit measured mean whole-frame RGB SSIM 0.97709338, with all limitations explained in the README.

Original artwork and soundtrack are reused and belong to their respective creators. The original reference video and private analysis workspace are not included. See NOTICE.md for details.

Validation: fresh full asset installation, all 1,520 texture hashes, five representative scene frames, playback/seek/sound controls, PNG export, and bundled Arimo font loading. The installer also passed corrupt-download, resume, path-traversal and link-rejection fixtures.
