Is there any potential in Magic Eye as a way to store or provide information that is only accessible to a human user, like say a kind of captcha, or are they too easy to reverse engineer?

I'd like to get a specific magic eye picture (it's the roses one with the floating heart) framed but the resolution is too low (using a website that frames pictures, when I upload it it's too low so they can't/won't do it as I presume it would be poor quality), is there a way to get one of these in hi res or is there a copyright issue with that?

The wall at the shop. Was spacing out while listening to people and saw the dots pop out! 🪄

Inspired by the recent post by u/StephenFerris, who provided the pattern.

I don’t think floating is the lace behaviour that’s bothering the seamstress but it’s on a sea of gold

Based on this autostereogram by u/lavaboosted

As said, it's just an experiment, It exploits the QR code self-correction mechanism. Unfortunately it's harder to visualize than the original, but I tried to stick to almost the maximum size that makes the code still scannable. It could be improved further by blending the autostereogram better into the QR code
