Cat Ears Pick Up on Brainwaves and Act as Furry Mood Rings For Those Around You

Of course these cat ears come from Japan, and of course they'll be on sale soon. Neurowear's Necomimi ears sit on a hairband (though don't let that put you off, guys!) and have sensors inbuilt for detecting brainwaves. Depending on the signals decoded by the sensors, the ears can twitch, wriggle or even flop down, letting everyone around you know your true mood.

Dangerous yes, but I imagine the types of kawaii people who'd buy the Necomimi ears won't be too bothered by that. [Neurowear via Japan Trends via Wired]
