CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." Typically the purpose of Captcha programs is to restrict access to online forums and accounts to humans and to keep automated "spam-bots" and other such malicious programs out. The "Turing" in the title refers to Alan Turing whose theories helped form the basis of early computing and who is famous for asking, “can machines think?" The character in this short video asks, “What am I?” What is the right answer to prove that you are human? 2011
