MotionCAPTCHA »
MotionCAPTCHA is a jQuery CAPTCHA plugin written by Joss Crowcroft, that uses the HTML5 Canvas Harmony procedural drawing tool by Mr Doob and the $1 Unistroke Gesture Regonizer algorithm (and the more recent Protractor algorithm improvement), requiring users to sketch the shape they see in the canvas in order to submit a form.
