Hi all,

I've been trying to write an OCR for the following captcha:

barafranca.nl/im-no-cheater/(Refresh will generate a new captcha)

I've managed to convert it to a black/white image with only 2 colours, like this:

And I've made a PHP script that is able to recognize certain patterns in the image, but hasn't been much help so far:

Do any of you have advice/tips on how to do this?
I've tried Tesseract and GOCR but they don't recognize the 3D pattern and come up with gibberish, both when training and decoding...

EDIT:
I found out this captcha is called teabag_3d, I've already managed to find the source code (PHP) for it.
Might be possible to reverse engineer it? Will check tomorrow.

Anyone willing to help?
I can also pay with PayPal if people here are up for doing this for money.

Thank you
