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.)

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

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 (?)

Now make it match push-ups so we can have true proof-of-work captchas.

The idea is funny, but doesn't work too well without a wider-angle webcam. (Arms get cut off from camera view)

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

This was great, but the crossed-arms example did not work.

Funny idea until someone takes it seriously and all of a sudden we have to strike a pose on Zoom

is it working?
