Are you human?
That's the basic question that any CAPTCHA seeks to answer by getting you to complete tasks that computers find difficult. Like typing the series of letters you see on the screen (used by many sites for registration) or adding two numbers together that some blogs use to moderate comments.
The thing that annoys me about most CAPTCHAs is that they're more difficult than they have to be to separate human from machine so I was thrilled to come across the CAPTCHA used by PassPack, an online password manager similar to Clipperz.
Take a look:
It reads: "Just click the black square to continue, thanks."
Isn't it the simplest CAPTCHA that you've ever seen?
Thanks to Tara Kelly, founder of PassPack for the tip! Although we didn't use it as intended.
