Imagine you're using the Internet and you see a CAPTCHA that you think is somewhat peculiar, like this CAPTCHA.

And basically, since we released it about three or four years ago, a lot of websites have started switching from the old CAPTCHA where people wasted their time to the new CAPTCHA where people are helping to digitize books.

CAPTCHA Project is something that we did here at Carnegie Melllon over 10 years ago, and it's been used everywhere.

So this actually has given rise to a really big Internet meme that tens of thousands of people have participated in, which is called CAPTCHA art.

So what we're doing now is we're taking all of the words that the computer cannot recognize and we're getting people to read them for us while they're typing a CAPTCHA on the Internet.

Another way of putting it is, is there some humongous problem that we cannot yet get computers to solve, yet we can split into tiny 10 second chunks such that each time somebody solves a CAPTCHA they solve a little bit of this problem?
