Blogger (and perhaps other Google services?) recently rolled out a new CAPTCHA system, involving segments of photographs alongside the more familiar bock of "wonky" text. The photographs are of walls and signs, and other such places where numbers and letters appear in real life, and it is your duty to figure out what the hell is in them. The idea of having humans doing the work of digitising analogue material via a CAPTCHA isn't new of course, but it's interesting that the Google system knows there is text there but still relies on a human to decipher it, or to double check it perhaps.
The photograph isn't part of the human verification process so you can actually write what you want for it. With the one above, I wrote "RobotClitoris" and my comment was published, so it's definitely not part of the test... unless of course, it actually is a robot clitoris? :-O
