This is a CAPTCHA in which you must id the center of subimages in a collage and then choose the correct caption for a second a photo. It took me seven tries to click close enough to the center of a
subimage. I'm human I swear! Lame implementation.

Spammers can get around captchas by getting users to solve the captchas for them in order to access porn sites

Negative captcha is described as tricking a robot to reveal itself rather than requiring humans to prove their humanity. The system uses CSS to hide an email form field.

In the past I've come up with ideas for software and find that the very idea is implemented soon after. So this time rather than getting down about it I'm going to make it work for me. I'll state
what I want to use and hope that its magically implemented. In order to uniformly support comments on my website I want a web service with the following features:
- Allow users to view and add comments for any particular URI.
- Use OpenID and optionally Card Space to
- Use a captcha system that's optionally cute or humorous.
- Has atom or rss feeds of the comments available.
- Doesn't require users to register.
- Doesn't require any extra steps for commenting on a URI that no one has commented on.
I'm going implement this now so no one go off and do it before me so that I can use it without having to do anything...

This is a Microsoft research project that uses kittens to prove your humanity. This is very similar to something I've linked previously:

Similar to the previous one where you prove your human by selecting cats here you select people that are hot or not based on the website hotornot.com.
