Our Analysis
If you've ever wanted that classic airport split-flap display — the mechanical boards that flip through letters with a satisfying clack — FlipOff gives you one on any TV or monitor for free. Open an HTML file, go fullscreen, and you have a retro departure-board display without spending $3,500 on Vestaboard hardware. Vanilla HTML/CSS/JS, zero dependencies. Realistic scramble animation with recorded flap audio. Auto-rotating quotes, fullscreen TV mode, keyboard controls. Responsive from mobile to 4K. Works offline. Just open index.html. 2.1K stars, all gained this week (+2,129/wk). The community is already adding features — Docker support, JSON config, emoji support, GitHub Pages deployment. The catch: it's a fun display project, not a business tool. If you want it for a restaurant menu, office dashboard, or retail signage, it works great. If you want integration with data feeds, flight APIs, or custom backends, you'll need to build that yourself. No configuration UI — you edit JavaScript or JSON config directly.
