If I saw that it wouldn't be worth my time to continue with the site. Next we'll be punching the monkey for a prize.

it's interesting but two things come to mind. Viewing it on this site makes it seem like it's great, but what about in context? If i came across that, I'm forced to think more than a capthca, just since it's so different and unexpected (maybe that goes away if it's very widespread). Also, it looks like an annoying banner ad game from orbitz or something of years back - that might make me avoid it, ignore or just not trust it.

in context we get about 40%-60% higher conversion rate depending on the use case and have over a 95% success rate. we have a lightbox mode that makes it really apparent what you are doing and only has you attempt a captcha after you submit and the form is validated.

Looks too much like spam.

Founder of Are You a Human here. Happy to answer any questions.

Nice! I am playing with the idea to put it on my site for fun. :-)

I use it as an alternative captcha for contact forms on some WordPress sites I run.

Met a couple people who work at the company (I'm in Detroit and think that's where it is based) at some startup events a couple years ago. That's how I found out about it.
