Now make it match push-ups so we can have true proof-of-work captchas.
hoomanmo•11h ago
is it working?

Duplicate of https://news.ycombinator.com/item?id=44274691 - I'm surprised it's even possible to send the same link twice in less than 24h (?)

I was expecting it to ask you to say some bad words which also could work as a thing languange models can't do (unless u finetune of course but as a joke captcha).

This was great, but the crossed-arms example did not work.
coolandsmartrr•9h ago
The idea is funny, but doesn't work too well without a wider-angle webcam. (Arms get cut off from camera view)

Funny idea until someone takes it seriously and all of a sudden we have to strike a pose on Zoom
viraptor•6h ago
It's a joke. The image provided is a perfect base for pose ControlNet https://www.nextdiffusion.ai/tutorials/how-to-use-open-pose-...

It's likely easier to generate a matching photo these days than process some of the visual captchas. So it would be pointless to implement.

That's why my website's dance captcha insists you do jazz hands and have a visible clock.

Not sure, but here in China many apps require you to perform a routine with your face, open mouth, blink etc.

I understand that the showcased project is meant as a "joke", but a few days ago I briefly saw a Recaptcha with a hand icon amongst its three other options. Curious, I clicked on the hand and it asked me for consent to record my gesture, with an assurance that the video would not be stored.

I've never been able to see the hand icon ever since and no one else seems to have documented its appearance. However, after some searching, I was able to find [1] (archived at [2]) which should serve as sufficient proof of this existing and not something that my mind hallucinated out of those "drink a verification can" memes.

(For people trying to visit [1], you should copy the square brackets at the end of the link, which HN leaves out when adding the anchor tag.)

Indeed, joke. No captcha will captcha me when it wants to film me with cold AI eyes. Or any eyes for that matter.
immibis•5h ago
You can say that until something important to you, like your bank account, insists on doing this or won't let you in.

Seems to be working if you percent-encode them:

Hey, another captcha that protects your site from disabled people!

Is this a quote from the song "Human" by The Killers? There was a song that went, 'Are we human? Or are we dancer?'
