[OT] Some questions on captchaby kiat (Vicar)

kiat has asked for the
wisdom of the Perl Monks concerning the following question:
Some questions regarding captcha outputs...
I've seen some that are really cryptic and difficult to make out (e.g. Slashdot, Hotmail). I remember when trying to make a post at Slashdot that I had make at least four submits before getting it right.
Then there are those that consist of just numbers that are easily readable - just like normal text.
What is the difference between the two? Does the purely numeric and easily readable one work as well as the cryptic one?
And is there a Perl module that generates a captcha output?
