An animated gif doesn't help, because the animation is really just a series of still frames, and breaking the animation into the individual frames and analyzing just one of them is trivial. Transparency doesn't help either, because to the program doing the OCR, 'transparent' is as much a color as blue or green, it's simply another index into the colormap.

    Not that anyone will read this after all this time... I see a way in which transparancy could really fark up an OCR. Using cascading style sheets, layer multiple transparent images directly on top of one another, so that the signal is broken across two or more files. If that's not enough, then you can add plain HTML text as well behind it.

    So you have to find multiple images, which can be placed anywhere (dynamically) in the body segment, and also add in some text that you have to parse out with a tokenizer. :-)

      What would be really impressive is if you had a set (maybe, oh, 153 of them) which were 9x17 with one point on each one filled in. Then, pick which ones you need and randomly layer them one on the other. You might hit some (silly) maximum in terms of the number of layers you can have, but it shouldn't be that bad. (In addition, you wouldn't have to stick to 1-dot pictures ... you could theoretically find all the dots you need and randomly break them down into a set of blanks, each with 1 or more dots filled in.)
