reCAPTCHA

I just came across this, and I’m pretty impressed. Basically instead of using random f’d up words for CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) it feeds up mangled scans of old books, and lets you digitize them one word at a time. Its an ingenious solution to an age old problem.
