The Neccomimi ears—an animatronic headband controlled through the power of your mind—that we first covered last year are finally coming to America! Designed and built by Neurowear, a Japanese fashion electronics company, the ears respond to their wearers emotions, perking up and flopping over depend on your mood. They will retail for $100 and be avialable at Comicon and through the Neurowear website. These are obviously quite awesome but what I want to know is, would you wear them? You know—in public?
