Dev Recreates MacBook Folding Animation in Browser, Open-Sources It and Mocks Paid Copycats

Frontend developer jh3yy demonstrated that Apple's iconic MacBook folding animation can be fully recreated in the browser — and even turned into a resident macOS app — while mocking people who sell such novelties for money.

Confirmed

• On September 10, jh3yy posted a pure-web MacBook folding animation, recreating Apple's 3D folding effect with CSS/frontend tech, riffing on the "your macbook has the folding animation at home" meme; the code is open source.
• In the discussion, he complained that people charge for little tricks he can reproduce on demand with an LLM in five minutes — and that buyers exist — implying such paid products have no real technical moat.
• The next day he open-sourced lid-plane, a macOS menu bar app that uses the MacBook's hinge angle sensor to keep the desktop at a fixed angle, progressively blurring it as the lid closes and re-anchoring when motion stops; the app remains clickable and retains keyboard focus.

Why it matters

The thread sparked discussion about the value of paid mini-utilities: as LLMs let developers generate equivalent effects on demand, apps charging purely on information asymmetry face disruption — while also showing how open-source frontend work can reproduce Apple-grade motion design.
