So let’s say, for the sake of argument, you wish you had cat ears. Real ones. That moved around in response to your mood, the way a real cat’s ears move.

I can’t really help you with that, but I can show you the next best thing: Necomimi Brainwave Cat Ears. These $50 kitty ears actually do move around in response to your brainwaves.

Like a mood ring.

Like a fuzzy mood ring on your head. This is Christy, and she’s going to help demo the cat ears today.

According to Neurowear, these ears respond to four different states that are somewhat confusingly referred to as High Relaxation, Focus/Relaxation, High Focus, and High Interest--I attribute the terrible names to an iffy translation.

Now, I want to be clear, they really do seem to work. I can get them to behave differently depending upon whether I’m concentrating or relaxing--but if you’re just wearing them around the house--as I am sure you are wont to do--you might not notice a lot except they'll seem to wiggle at random occasionally.

Here’s what it looks like. The ears themselves come off, and you can replace them with others at about $10 a pop. There are leopard ears, devil horns, and others.

It runs on 4 AAA batteries, and unfortunately, there’s no good way to hide the fact that you’re wearing a metal apparatus on your head. This sensor has to be in contact with your forehead, and this clips to your ear. Sexy!

What do you think, Christy? Good for kids? Cosplayers? Would you buy one?

Christy says: "I'm not sure if I believe that these ears truly are in sync with your brain. Though it sure is fun to pretend and to have fun with it, especially at a party or with a big group of friends or family members. It may be a little too advanced for kids. And cosplayers -- oh man, it’s good. Really, really good. I say, this would make such a good gift for the right person. I know you could think of a few people, I sure can!"

The Necomimi Brainwave Cat Ears are available at for about $50.
