[Michelle Clark]

This sounds wonderful. With all the trouble we have with those things, I
intend to check it out.

Hello:

     Jonathan Lazar at Towson University came up with a CAPTCHA called
Soundzright (sp?). It works by asking the user to press the spacebar when a
particular sound is heard. For example, it might ask, "Press space when you
hear the dog bark." The user then hears a series of sounds such as breaking
glass, a baby crying, piano music and a dog barking. The sequence repeats
three times. If the user presses the space at the right time, the CAPTCHA is
solved.

I have also seen logical CAPTCHAS such as which number is larger 6 or 5? 
Hope this helps.

Regards,
Robert
