#13That is 1. Cursed, and 2. Definitely in the right place here.
This is the stuff that I come here for.

#14If the online porn industry hasn't used it, it's probably worthless. Still funny, though.
Re: Regressive JPEGs
#15Nice! I think you can approximate timing somewhat, by making your web server create the "jpeg" on the fly and send it to the client in timed chunks. The source could even be a webcam, so the "jpeg" would go on forever.
A lot of IP cameras already do this via https://en.wikipedia.org/wiki/Motion_JPEG

You can use Service Worker to emulate a slow connection :)

#17I wonder if you can do this in JPEG-XL. I know that that has actual animation support, but this would be a different thing.

#18insanity of content aside, that's a really nice website. Kudos.

The format supports progressive decoding but IIRC none of the current browser implementations support it. The first Chrome and Firefox implementations did, and I think it's on their roadmap for the new Rust implementation. No idea about WebKit/Safari.
Edit: the format also supports region-of-interest decoding and I suspect you can make some cool maps or fractal images with both features. But I think they're not quite prioritizing implementing that right now.

#20Adjacent advice:
I've recently played with opengl and jpeg turbo and I wanted to display images fast. I don't remember exact numbers, but enabling progressive for a jpeg was a significant slowdown for decoding.
So if anyone like me is stuck with the old school advice that progressive is an nice to have, it's likely not. I personally don't remember any visual progressive image buildup in like decades, so it's not doing anything valuable at all.
