Cool! That's a good idea. I may implement it and similar things soon. Just for posterity, I independently invented CAPTCHA, I think a year before the CMU kids thought of it. I even began filing a patent while at my startup in the late 1990's, but we ran out of money. I should have continued, although the situation was murky. Imagine my surprise a couple years later at the IJCAI AI conferences in Acapulco when the CMU team presented CAPTCHA at an extra presentation at the end of the conference. I went on a lark because the point of the presentation wasn't clear until I was sitting in it. Just one of the many things I've thought of / invented that I didn't capitalize on, or give away in a timely fashion. Par for the course; many people will have similar ideas at similar points in time.
