"Captcha images are commonplace on Web site
applications and forms. With its latest framework, Zend is
introducing a new Captcha Form Element that can provide multiple
types of Captcha mechanisms. Among them is Captcha integration for
something called FIGlets, group of large characters built out of
ASCII characters that outline a letter or word. An outline of
cartoon character Snoopy on his doghouse is one popular example of
a FIGlet."
