Weirdest gadget ever!?
A company called Necomimi has what may be the weirdest technology product I've ever seen in my life. The product is called the Brainwave Cat Ears and claims to read your brain waves to alert people of your mood based on how the ears are positioned. The two big ears are on a headband that the user wears and the sensor goes against the forehead.
The ears wiggle the back-and-forth when the wearer is highly focused and highly relaxed, stand straight up when something catches the user's attention, and droop down when the user is relaxed. You can purchase your own cat ears now for $99.95.
