3D-Based Captcha- Friendlier to Humans

See, this is cool: 3D Captcha. I hate doing math and squinting at those squiggly letters, but, thanks to my being a human and not a robot, can tell the difference between a picture of a camel and a picture of a fork. Therein lies the genius of 3D Captcha.

(Captcha= Completely Automated Public Turing test to Computers and Humans Apart, aka "that little box you have to fill out to prove you aren't a spambot")

By using objects, you raise the number of potential combination, which would make the system harder for a bot to figure out.

Similar to Hayward's idea, this new technology relies on our ability to identify objects in 3D instead of using alphanumeric characters. YUNiti's 3D Captcha, however, has three objects in the challenge and extends the list of images to any object, not limiting it to animals as in Hayward's idea. This increases the challenge's level of complication to prevent computers from successfully making the correct guesses.

Though I'm not sure what it means when YUNti's Captcha interests me more that the site that's hosting it.
