OCR with a really tricky captcha..

Struggling with
http://barafranca.nl/im-no-cheater/
(Press refresh for diff catpcha)
Working with imagemagick and managed to find a good library of useful functions.
Got the image camera perspective working mostly:
Now Gunna try finding the standard diviation of the area within each square and filter out everything except the top 5% and bottom 5%. Hopefully this will leave an outline of the characters within the captcha.
If this doesnt work i figured Hough transformation and flood fill algorithms would be the obvious next things to look into.
Any ideas? (php only)

Nothing. That's why it is in the random category.

There aren't many forums where the community are willing to share ideas for stuff like this. It's a long shot posting here, but if it isn't appropriate, i'll take it down.
Anyway, nobody has any ideas how to tackle it? :S
