Elder-plinius – The Fable 5 Showcase A developer used a single prompt in Claude Code to exhaust a week's worth of Anthropic API credits in one day, spawning approximately 275 parallel Claude Fable 5 subagent runs that produced 57 self-contained creative web demos. Each demo is a single index.html file with zero dependencies, covering generative art, simulations, physics, worlds, sound, and play, all built and QA-verified by fleets of Claude Fable 5 agents. This repo is the answer to a simple question: "What happens when you prompt Fable to use up an entire week's worth of Claude usage credits at once?" 57 self-contained creative web demos — generative art, simulations, instruments, and procedural worlds — each one designed, built, polished, and QA-verified end to end by fleets of Claude Fable 5 agents running in parallel, in a single day and from a single prompt. Every demo is a single index.html file with zero dependencies — no build step, no CDN, no frameworks, no network requests.

Thumbnails were captured by rendering each demo in a headless browser; the gallery embeds them as data URIs so it stays completely self-contained. ok i have a challenge for you i need to use up my anthropic api credits for the week in one day, and ONLY on fable 5 lets see if we can't build something that leverages our claude code cli thats authed to build a bunch of epic demos for fable 5 of all sorts of different complex cool creative projects leverage fable 5's full creativity and intelligence until our credits are gone tons of stuff in parallel index.html — the gallery searchable, category-filtered; thumbnails embedded inline
