Re: Example of accessible CAPTCHAS that work well

Two principles to go by here:

        accessible security (can a user with a disability, can assistive 
technology, can . . . use the security mechanism?) 
        and
        secure accessibility (when using the assistive technology, when 
using the alternative, when , , , is security compromised?)
