Berlin-based artist Aram Bartholl created these cards by uploading the individual images to MOO Cards, who specializes in making tiny business cards, each with a different image. While the cards ask the question “Are you human?”, I’m not quite sure what would happen if you handed one of these to a robot. Would it self-destruct? That would be cool.

Did you know CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”? I always thought it meant “Cats Acting Cool Taste Chocolate Ham Animals”. Mnemonics, your dear, dear friend.
