It uses the GDlibrary and PHP sessions. No MySQL is needed. Please see demo the at http://evolveradio.com/cl ockedya It is fully customisable and comes with 25 clock faces which you can easily replace with those of your own design. The clock is also randomly rotated through either 0, 90, 190 or 270 degrees, though this feature can easily be turned off, if you prefer not to make things too difficult. The reason for a selection of moire clock faces is that it makes writing a generic algorithm for solving the captcha, more difficult. I believe this captcha is also immune from histogram analysis. It may present a problem for sufferers of colour blindness, but this could be alleviated by using a more conservation selection of clockfaces.<<less
