OCR and neural network in Javascript

    A certain Shaun Friedle wrote a curious javascript that automates captcha recognition on megaupload.

    A couple of interesting features of the script:
    1. HTML 5 is used; the javascript getImageData function for working with pixels;
    2. an artificial neural network is used for recognition and works quite accurately.
