These captchas reminded me of this fun but potentially frustrating captcha where you follow a shape, in a Korean game: https://orangemushroom.net/wp-content/uploads/2024/05/find-t...

Hey, that's easy, it's をこかすや. You could probably make some funny "CAPTCHAs" for otaku/weeb stuff in this vein. Though, I'm not sure there's much you could do that would not be easily solved by Gemini or whatever frontier models, but it would be entertaining anyway.
