If you’ve been online, you’ve at some point encountered some kind of Captcha, where you have to decode warped-looking letters and numbers. I don’t know about you, but these have been getting harder for me to decipher (and I hope that doesn’t mean I’m losing my humanity).

Today, there’s a new kind of Captcha available that has a new way to determine if you’re a person or a machine. NuCaptcha uses animation, so the letters and numbers can be relatively easy to read, but hard for spambots to figure out.

A colleague of mine over at Speaking of Faith has been captured by Captcha recently.  He wrote about a project by a Danish artist who’s taking these Captcha codes and juxtaposing them with grafitti. The project is called, “Are You Human?” and is worth a look.
