Damn right I'll be using this on some of my sites. Nifty idea.
[hr style="width: 100%; height: 2px;"]A new, jokey-but-cool proposal for reducing automated signups uses kittens instead of scrambled text to keep bots out and let humans in. CAPTCHAs are tests that try to figure out if a web-page is being accessed by a program or a person by requiring a task humans are better at solving, like typing some distorted letters into a box. They're often [a href="http://www.boingboing.net/2005/08/23/pwntcha_defeating_ca.html"]breakable with code[/a], and when they're not, they're [a href="http://www.boingboing.net/2004/01/27/solving_and_creating.html"]breakable with porn[/a].
The KittenAuth test puts up a mosaic of cute baby animals and asks challenges the user to click on the kittens. This is easy for sighted people, pretty hard for software, and a little too incongruous to be a likely candidate for porn-based CAPTCHA solving. Ingenious!
