I went and had a look at:
http://en.wikipedia.org/wiki/Captcha
as I have CAPTCHA on my web site contact form, but wondered what the letters really meant, and see Alan Turing gets a mention.
But, have a look at the third series of alpha-numeric pictures on the above page. Maybe I am getting old, but some of these are impossible to read, and when they decide to enhance them with back ground drawings, well, how does a human get to actually contact anyone in future?
I would find a mathematical question a lot easier, even if it was 3 or 4 levels of operations, with decimal point answers.
Cheers Don...
