The Human Brain Cloud is both an online game and a greater experiment. As visitors to the website take part in its online, interactive word association quiz, the answers are logged and used to create a visual network based on the most common and the most uncommon answers. There's no serious research behind it, but rather just a passing distraction for both web surfers and Human Brain Cloud creator Kyle Gabler who's curious to see what the most common, subconsious assoications exist in our society.
