You’ve always wanted to have cat ears that react to your brain waves, right? No? Well, here they are anyway, nine minutes of members of the public with big fuzzy wiggling cat ears:

What it doesn’t show is why you’d want this. For those of us who blush easily, it’s all we can do NOT to show our emotions when we don’t want to. I suppose that something that reacted to emotion would be good for people who, through mental disability or other inability to communicate, can’t show their emotions. For the rest of us, mind-controlled devices hold out a lot of promise, but it would probably be best if they didn’t take the form of fuzzy cat ears that droop when you concentrate.
