The CAPTCHA Project..

"A CAPTCHA is a program that can generate and grade tests that:

  • Most humans can pass.
  • Current computer programs can't pass. "

You've seen this before - think of systems you've used that ask you to access a web page and read text off that page that was somehow obscured, then feed it back to the system to prove that you (and not some automated agent) are in fact there. But did you know they had a name? - SWL

Creating a link to this site, say like this one, actually creates a new page on that site, much like how using a WikiWord works within a wiki. Apparently uses trackback and ping back as well. Curioser and curioser. - SWL [EdTechPost]
