PWNtcha is a project that tries to crack captchas. Their main project page has a pretty good overview of the various varities of captcha out there. James first turned me onto CMU's Captcha Project several months ago when we were talking about ways to stop comment spam. Luckily, my site doesn't appear to have been infiltrated yet. I'm sure it's only a matter of time...
