I was researching the site a little bit. It looks like the neurosky Neurofeedback device with plush ears. Yes, they are cute, but I still have to look what I can do with it.
I'm quite into neurofeedback games and stuff, so if there is an interesting interface and a reasonable prizing. maybe.
But for males plush ears are a little strange.
I love the idea: the sensor checks your brainwaves and according to your state the ears will signal. if you are interested you will prick up your ears.
