Check the article link below for more details and a scary screen shot (via Technology Review, which notes “A series of apps use your brain waves to power them. Welcome to the era of DIY EEG.”)
The company's first app launched in December. Tug of Mind purports to train users how to relax under pressure. After uploading a headshot -- of an ex-boyfriend, say, or a mother-in-law -- the photo is transformed into an angry avatar that screams insults (you prerecord the message). The avatar starts smiling if the player remains calm; keep it up and the game is won. Price tag: $4.99.
