There have been different experiments with people hooking electrodes up to his/her [or someone’s] face with the result of controlling some sort of twitching facial movement from a third party. Usually, it’s about as useful as it sounds. It’s sort of like a more dignified “why are you hitting yourself.” This video makes it a little more interesting as it takes several different people and syncs up the twitching to a musical background for a total display. It’s kind of an interesting way to use this technology, but watching it for a full four minutes makes me a little uncomfortable.
