| 3 | PWNtcha stands for "''Pretend We’re Not a Turing Computer but a Human Antagonist''", as well as ''PWN capTCHAs''. This project’s goal is to demonstrate the inefficiency of many captcha implementations. |

| 9 | I created PWNtcha in 2004 as a personal research project, but only published my results, not the program itself. Given the number of captcha-breaking software available for sale now, I changed my mind and decided to publish the PWNtcha source code. It can be downloaded from Subversion: |
| 10 | {{{ |
| 11 | svn co svn://svn.zoy.org/libcaca/pwntcha/trunk pwntcha |
| 12 | }}} |
| 13 | Note that PWNtcha is now lagging 3 years behind captcha technology and is therefore no longer a very interesting piece of software. |
