I've been all over the web trying to find a randomly generated math captcha (or just math) for verifying a simple contact form. Lots of 'close-but-no-cigars'. One of the links Googled led me here.

Any possibility of getting the source for your form and math?

It's a joke... there is no math CAPTCHA that hard. but there is very challenging math captcha out there. hope you find that fun.
Most college professors would need at least an hour to solve math CAPTCHAs like mine, unless they just cheat by using computer to calculate the approximation and take a good guess.
