FlipOff is a free, open-source web app that emulates a classic mechanical split-flap (flip-board) airport terminal display — the kind you'd see at train stations and airports. It runs full-screen in any browser, turning a TV or large monitor into a beautiful retro display.

No accounts. No subscriptions. No $199 fee. Just open index.html and go.
