Different types of Captcha's you've seen.

I just completed a Captcha where I had to "make a sundae" out of some floating ingredients. It's definitely the strangest one I've seen so far.

Have you seen any other interesting captchas?

We've developed a captcha system for an R18 membership site, that was pretty interesting..

No bot can get past it, and has lasted 2 years so far.

I can imagine that would be quite interesting Care to elaborate? What does solving the captcha involve?

I've seen one a few time that depicts an animal among colored dots asking what you see. A couple time I incorrectly type in goat to see it refresh hoping to see a goat. Normally they're common farm animals, but I did see a camel once.

I think it was on one of the faucets where I saw another cool one. There was a twisted picture with a scrollbar below it and you had to move the scrollbar until the picture was close to the original.

actually thats probably the worst captcha as you can defeat it with a simple algorithm...

The SolveMedia captcha which is either a standard captcha or an ad like:

"MasterCard Describe this brand with any word(s):"

If the picture is relatively unknown, I can't see how it would be easy to cheat.

Could you explain how a simple algorithm could defeat it?

just measure if the picture is out of focus (ie, not sharp) and since there is only so few possibilitys this will be a matter of some ms
