   Neat. In the thread someone mentions that it's possible to derive the 
answer for the old-style street number captchas using tesseract [1]. 
Interestingly, there is a version of tesseract in javascript [2]. This 
is probably not especially useful for the current "select all boxes that 
contain one pixel of street sign" Recaptcha system, but if there were a 
way to trigger the old behavior, these techniques could be used
