A hover-based clock, such as the one in Jane Ori's CPU Hack, is fast and stable, but requires you to hold your mouse on the screen, which some people claim does not count as turing complete for whatever reason, so I wanted this demo to be fully functional with zero user input.

That hover clock post is from 2023 and the "some people claim does not count" post is 2022. They were probably talking about the ones that make you check thousands of boxes to drive the logic forward.

Anyway, very cool advancement.

Completely unrelated but somehow unsurprising:

Zero-day CSS: CVE-2026-2441 exists in the wild - https://smackernews.com/item/47062748 HN - February 2026 (233 comments)

I see CSS random() is only supported by Safari, I wonder if there's some side channel that would work in Chrome specifically? (I guess timing the user input would work)

CSS should NOT be becoming turing complete. Nor any other DSL.

I'm curious to know what you would rate as the most important features to make this work? It seems like calc+if do a lot of the heavy lifting, but the new function syntax is what makes instruction lookup tractable.

Also: wow.

I get the feeling some people just hate the web.

Can it mine bitcoins or run worms?

Sorry to see internet regressing to Internet Explorer days.
