Interdimensional Podcast

An infinite podcast you can interrupt with a topic. Santa and Satan keep talking, find a questionable connection, and take the conversation somewhere new.

Built with fal: MiniMax H3 Max Turbo generates each speaking shot from a character image, while Gemini writes the next exchange.

How it works

• Two fixed camera angles, generated speech, and short 5-7 second turns.
• Three clips buffered before playback, with up to four upcoming shots prepared ahead.
• Audience prompts steer the next unwritten exchange without cutting off a speaker.
• Pause, resume, fullscreen, captions, and an optional studio details panel.

Run locally

Requires Node.js 22.13+ and a fal API key.

npm install
cp .dev.vars.example .dev.vars
# Set FAL_KEY in .dev.vars
npm run dev -- --host 127.0.0.1 --port 3212

On PowerShell, use Copy-Item .dev.vars.example .dev.vars instead of cp.

Open localhost:3212 and select Tune in. Generation uses your fal credits. The key stays on the server.

Under the hood

React, TypeScript, Vinext, and a local Cloudflare Workers runtime. Character images are generated once, then reused for image-to-video. Edit lib/show.ts to change the cast, opening, voices, and writing direction.

The buffer smooths playback but adds a delay to audience requests. Generation can still stall or be rejected. Captions show the script; generated speech and voices can vary. Stop ends new submissions, while jobs already sent may finish. Reloading clears the session.

Checks

node --test tests/engine.test.mjs
npx tsc --noEmit
npx oxlint app lib components/player.tsx
npm run build
