reCAPTCHA: Stop Spam, Read Books

This is by far the coolest captcha service ever. (Blogger, you should pick this up) Out of Carnegie Mellon, this service aids in digitizing books. It gives you two words to type, the first is a known word, the second is a word that their OCR algorithm couldn't figure out. If you get the first word right, it assumes that you also got the second word correct.

I think it's a fantastic idea, putting captchas to a good purpose. :)
