Dan:

I've tried that scheme before, but it was shot down by the 
accessibility movement. No matter how simple the questions, it was 
problematic.

Eric Meyers once had "What's the color of an orange?" for access to 
his site, but then he took off all restrictions. I think it might 
have been too political, but I wouldn't expect him to comment either 
way.

I also developed a scheme that said something like "Pick the third 
letter" (TIMY), but then it didn't deal with the dyslectic very well.

CAPTCHA looks simple, but it's not.

Cheers,

tedd
