Now you can let everyone know how you're feeling without having to say a word. These ears by Neurowear supposedly pick up your brainwaves and move based on your emotions. Are you excited? They'll perk up. Are you relaxed? They'll lay flat.

What a great way to freak people out. They'll either give you odd looks A) because you have moving cat ears on the top of your head or B) because you are wearing cat ears.

Oddness aside, it's cool to see what technology can do. As if Twitter and Facebook don't give us enough ways to broadcast our emotions to the world, now there might be even more blatant ways to do so.
