Cool, fun visual idea

jama211 on HNNice one, the good (great?) thing is that you can save this as a plain old html and you've got the whole code :-) It hasn't got any type of license included or any other info as…
NKosmatos on HNNeat! I've seen stuff like this that works as a magic eye thing. So you cross your eyes (or make them parallel, depending on the type of image) and it makes a 3d animation appear…

From 2 comments

Questions
What does the text look like and why is it not visible for some users
From 2 comments
Could someone please post what this disappeared bit is supposed to look like? Looks legible to me when I screenshot and open in Preview on MacOS 15.6.1 (Firefox).

axiolite on HNI've found taking two screenshots and adding them as separate layers works well, and then setting one as Difference, and then tweaking the opacity. Here it is in Pixelmator Pro:…
