<a href="http://dimgord.com/RUH" rel="nofollow ugc">RUH Captcha</a> is a WordPress plugin that helps 
filtering out all robot attempts to register/comment. 
A human being can identify easily (after a few moments of thinking, of course) two closest matching objects from nine. Standard version comes with a static set of pictures, stored in my database. Customization is possible, please contact me if you are interested. Also, some security improvement may be added.
