A quick definition: A CAPTCHA is a little test to make sure that forms submitted on the internet are filled out by a human, not a machine. Often says you ahve to type characters from a distorted picture.

I used to get a lot of spam in a few forms I ran until I coded my own CAPTCHA (before the reCAPTCHA days).

I'm trying to do a new script. I want a slick, unintrusive feel without the cumbersome CAPTCHA. Can anyone think of any unique ideas?

I do know NoBot from the AJAX toolkit but i'm trying to do this in Linux & PHP.

Cheers.
