The Fable 5 Showcase is a gallery of 57 small, self-contained web demos, ranging from generative art and physics simulations to playable instruments and procedural worlds. The whole collection came out of one experiment: the author asked Claude Code to spend an entire week's worth of Anthropic API credits in a single day, using only the Claude Fable 5 model, and to build as many creative demos as it could along the way. Each demo is a single HTML file with no outside dependencies. There is no build step, no content delivery network, no framework, and no network requests once the page loads, so anyone can download one file and open it directly in a browser. The demos are grouped into loose categories. There are simulation and life themed pieces like a flocking bird animation, a particle life system, and a slime mold simulation. There is generative art such as a fractal explorer, an I-Ching oracle, and a tarot card generator. There are physics and motion pieces including an orbital mechanics sandbox and a black hole lensing visualization. There are larger virtual worlds like a gothic cathedral and a small pocket planet, plus sound and music toys such as a playable circle of fifths, and lighter curiosities like a pinball table and a falling sand terrarium. To build all of this, a single starting prompt in Claude Code fanned out into roughly 275 separate Fable 5 agent runs working in the background at the same time. Each individual demo went through its own design, build, polish, and quality check steps before being added to the gallery. Thumbnail previews were generated by rendering each demo in a headless browser and embedding the resulting images directly into the gallery page, so the whole showcase stays self-contained with no external image hosting. The repository includes the main gallery page, a folder for each individual demo, and a folder of the captured thumbnail images. The README does not mention a specific software license.
