Always strive to learn something useful. --Sophocles

It's interesting. We're used to being presented with a Captcha box with squiggly letters that supposedly only humans can decifer (which software could in some circumstances), now Google will be presenting us with a checkbox that says 'I am not a robot.'

The little square that the text and box are in is monitored, and Google says that the characteristic of a person checking that box is unique and identifiable. I just wonder how long it will take spammers to figure out how to make the mouse pointer jiggle a little bit before checking the box. I also wonder how this will work with assistive devices for people who don't use conventional pointing devices.
