Hi Antonio,
Nice proposal and take a look at this: Breaking a Visual CAPTCHA http://www.cs.berkeley.edu/~mori/gimpy/thanks for the link, I'll later put that in the documentation! In their February 2004 contribution to ACM journal, von Ahn et al. mentioned that there is an ongoing battle between creators and crackers of CAPTCHAs, so it's an interesting field to watch. But as long as it keeps _most_ id*ots from spamming weblogs, it's ok if it can be theoretically broken IMO. :) Regards Christian
