Inspired by a viral post, the author used Claude Code + OpenRouter ($6, 10 hours, 75% of his weekly Opus token budget) to produce a 64-second launch commercial for his iPhone app Cleanmail: a pure JavaScript canvas animation rendered to MP4. He published the full prompt, which includes: a $10 budget cap with balance checks and cost logging in README.md; single headless browser instance with frames piped straight into ffmpeg (never thousands of PNGs) plus memorypressure checks; versioned releases/V1,V2 folders with nothing overwritten; and fully codified brand rules (exact hexes, fonts, radii, motion curves, wording taboos) in BRAND.md and the prompt. Key advice: run in stages and approve creative direction incrementally rather than one-shotting. Free 2-week trial of the app linked.
