However, this idea defeats the purpose of a Captcha. There is only a finite list of companies one would want to advertise (or a fun list of words to make people type) and it would be trivial to write an attack against any site doing this. Even worse is that the captcha's used in the above example (one color and no distortion) are easily hacked with OCR software. Interesting idea and a nice try.
