Programming and other stuff
The problem with captcha libraries is, that they are not able to generate new content like humans. So I got this idea to write a captcha library for Django that asks users to draw more material when needed. The actual captcha is to choose correct objects from a 4 × 4 grid.
I don't know if the idea works, but at least it's kind of fun to play with. If you got interested, you can find a working demo from here: http://captcha.henu.fi/
Sources for the library can be found from here: https://github.com/henu/django_draw_captcha
