I think this is an intriguing approach - particularly for use cases on mobile devices. We display captchas as necessary through MobileFrontend when they are triggered, but the mobile experience is horrible (arguably the whole captcha experience is horrible regardless of the medium, but that's another conversation). As long as we need to surface captchas, something non-text based, especially if it didn't require typing, would be preferable.
