Make risograph films and posters with Claude Code and the riso-windowseat kit

In this repository, sevenevesai/riso-windowseat, Claude Code developed a kit that enables users to create risograph films and posters without relying on AI-generated animation video prompts. Instead, the project utilizes a single index.html file containing Canvas 2D and Web Audio, with no external libraries, fonts, images, or network calls.

The repository includes nine films, each 1080 x 1080 pixels at 30 frames per second, as well as two print series exported at 2160 x 2160 pixels. These films, Window Seat, Roost, Held, Nonpareil, Eclosion, Passenger, Standby, Lumen, and Emergence, are all pure functions of time, allowing users to inspect any moment exactly and ensuring the MP4s do not drop frames.

To set up the project, users need Node.js 18 or later, along with Claude Code. After cloning the repository and navigating to the "riso-windowseat" directory, users can install dependencies and run tests using npm commands. Claude Code is then opened in the repository root, and the session is guided by the CLAUDE.md file, which outlines the contract and commands, as well as the specified skills (.claude/skills/) for creating films, still images, and scores.

Claude Code can be prompted to create a 40-second risograph film of a lighthouse keeper's night, a risograph poster of a heron on a pier at dusk, score an existing film, or extend Window Seat with a new scene. Once edits are made to a film, any occurrence of Math.random() calls or missing window.__riso is flagged to ensure deterministic renders.

The project follows MIT licensing, but the piano recordings in Window Seat are CC BY 3.0 (with credit required), while Eclosion's wing geometry is CC BY-SA 4.0.
