Yeah, I literally said in my comment that I'm aware it doesn't make much sense :) I agree with you! I just saw it on the Duo and fancied seeing it on my Mac. But if you try it, or watch the animation closely, you'll see I made some changes to the effect. For the Mac, my idea was that the lid is just a kind of window into a fourth-dimensional space where the actual screen lives. When you open the lid, you're moving it closer to this "ethereal" screen until the two attach.

Because the person found it fun is a valid reason. It’s kinda cool!

I’m pretty sure Apple will do this in macOS 28, and there are some details to improve (guessing from the animation, haven’t installed it). But, people can and should do things just for fun.

OP probably enjoyed the project and likes how it looks. Why does there have to be an "appeal" other than that?

Like virtual glass, water droplets, etc., the effect is mainly just to be flashy and show off. Any usability rationalization is after-the-fact.

I don't know either... But it is the first time I've ever seen the parallax effect adding value to a homepage. Great job in that regard!

I understand there are grey areas in what you say, but I'm not a lawyer.

"Built with GPT-6 Astra" it may mean you asked "look at the iPhone Duo page and build me the folding effect but for the MacBook", or that you ideated how it should look, what tuning options should have, discuss performance optimizations, and so on.

I do make the distinction between those two, and for the latter, which was my case, I do think there's claimable copyright.

However, I'm not interested in claiming anything regardless I would have the right or not. What I do intend, is that if somebody else builds upon this work, they do it within the OSS space as well.

If that can be legally enforced or not, well I won't stress about it.

Yeah, I had my suspicion whether it would work universally. It uses WebGPU, fallbacks to WebGL2, and if that fails too it should fallback to a fixed image. Thanks for the heads up, I'll check it out over the weekend!

That's true! On the Mac there's only one glass pane (the other half is the chassis/keyboard), so my idea was that the lid is just a kind of window into a fourth-dimensional space where the actual screen lives. When you open the lid, you're moving it closer to this "ethereal" screen until the two attach. As you close it, the screen stays fixed in that "virtual" space, so the angled glass distorts the light.

I'm aware it may not make sense physics-wise, eh. :)
