I'm adding the design list. I talked about this recently with a couple of the designers.

hello,

These are some approaches i can think of instead of a text based captcha.

The image idea where users are asked to spot the odd one out like demonstrated or find all the similar images like mentioned in herehttps://www.mediawiki.org/wiki/CAPTCHA .

Also a picture with a part chipped in could be shown and chipped pictures could be given as options

like find the missing part from a jigsaw puzzle.

The image which would be shown is http://imgur.com/uefeb08

http://imgur.com/KEJqCg3 is the picture which would be the correct option.

The other options could be rotated versions of this , which would not be so easy for the bot to match. (unless it somehow worked some digital processing algorithm and matched the color gradients or something like that).

This is a good option for people who do not know english or are illiterate and maybe would not understand questions like : is this a bird , plane , superman? after being shown a picture.

Tell me what you think

(Sorry to upload those images on imgur. i dont know how to put them on the wiki .Hope that is ok)
