It was written as a proof-of-concept at a time when there were really no other good php captcha scripts around (2005).
It remained for a long time of the best free spam filters in the wild due to its tricky image and text rendering technique.
The CAPTCHA can output as JPG, PNG or GIF, has brute force protection, is open source and is totally self-contained.
There is no need for SQL databases, PEAR, or anything beyond PHP and GD.
