Yeah thats too easy.

Just remove the non moving bits (gif animation does that anyway) and you've got your letters.

Now get the background moving, make it easier to read and give it the ability to be generated in 1 sec on a Celeron then you have a Captcha.

indeed.

even if the gif weren't optimized and redrawn each frame in it's entirety rather than smallest changing area, it's easy enough to simply overlay filter one frame on top of the previous to erase all identical elements, and you're left with nothing but the moving peices.

Having the rest of the background move would help, but would make it almost incomprehensible to most users, and would be impossible to dyslexic users (not to mention, the current version probably already *is*)

When performing some online banking tranactions, I have to click my mouse an onscreen QWERTY keyboard in order to "type" in the characters.

This sounds promising to me. Are there bots capable of this sort of mouse interaction?

There are not any programmed to do that right now that I know of...but it should be pretty easy to make one capible of that...

it uses javascript to do it so yes i should not be that difficult for and expert programmer now if the function names it used changed every time then the bot would have a real hard time

What if the bot would have to parse not only a image but also Javascript and CSS to reconstruct a image in order to OCR it?

People with older browsers are the minority and they can just e-mail the admin.

Well they'll just have to bite the bullet and download Firefox then.
