cartechboy writes "Two Ph.D. students from MIT have created a keyboard accessory, the Pavlov Poke, that shocks you every time you go onto Facebook. The project comes as a result of the students finding the waste over 50 hours a week combined on the social network (instead of working on their dissertations) So the pair created an Arduino-based keyboard hand-rest that shocks computer users who spend too much time checking the social network. The hack is 'intended to generate discussion' — not actually turn into a business." Inventor Robert Morris describes it as "something of a joke," but I'm sure there's a market out there.
