And this particular captcha is really useless. I just played around a little with gimp and used only a gaussian blur, the color level tool and some cut and paste to make the characters perfectly readable by GNU OCR: http://organiceit.lanscene.at/~nine/captcha-enhanced.png And gocr cought it right on the first try. To automate this is would be trivial, no magic involved. IIRC Wikipedia links to a good site, trying to do this. Good captchas that are harder to crack would use different colors and twist and distort the letters. Unfortunately the captchas that are hard to automate are also becoming increasingly hard for humans to get right...
