You know how on certain sites, when you sign up/log in, there's an image with letters/numbers (often with lines streaking through or otherwise curved really weirdly) that you have to type in a text field to 'prove you're human'? That image is a captcha ^^ First example I can think of is fanfiction.net (there's a captcha when you log in)
