Just came across an interesting site, courtesy of /. PWNtcha is what is known as a captcha decoder, and just in case you have no idea what I'm talking about, a captcha is one of those image verification tools used to defeat comment-spam bots. Kind of like what's used in the comments section of blogger. Click on "comments" to take a look. (hint. hint.) The site basically explains how captcha techniques work, and is well worth a visit.
