simpelCaptcha (current version: 0.2)

SimpleCaptcha allows you to drop in an easy-to-use and understand captcha implementation for helping to curb spambots on your system. The plug-in makes things very easy for you with a limited amount of setup required and standard xhtml and css classes in place to make changing the appearance super easy.
