Does anyone know of a captcha service, whether external (any) or internal (bonus points for ruby on rails) that is just for matching images, like 2 dogs or 3 cats? I am not looking for anything heavily secure anyway. This is for user registrations.
A:
Perhaps any of the services listed on this list may help you? They include ones like "click the one that is a house".

Nice list! Esp since the original captcha system is so broken (decaptcha web-services linked to chinese workers who don't need ot know english to just do letter recognition).
