I have seen some interesting captchas over the years, and some of them intrigue me enough to find out why they are what they are - the history - the mythical meanings - all very interesting to me.
This paste will serve as my master index to all of my captcha research... if you want a free education on food, health, history, interests, and many other topics, just reading some of these will broaden your knowledge and your English language skills.
