NeuroSky's Necomimi. Necomimi is a headband with brainwave cat ears that move according to the user's moods. Powered by NeuroSky's ThinkGear technology, Necomimi gives people a chance to express their moods in real time. The cat ears use three emotional states to create cat-like reactive movements that show how interested or relaxed the wearer is. The ears can droop down or stand up or wiggle back and forth according to a person's feelings at that moment. The brainwave cat ears retail for $100. See them at www.necomimi.com.
