USB Brain Massager

Every time I walk past one of those weird infomercial stores in suburban shopping malls, my hand automatically goes to those brain massager things that you can stroke your head with. I don't really believe it improves circulation and makes you smarter (or whatever they claim it does), but it feels great. Well, in Japan, we have the same thing, except it vibrates and is powered by USB.

Also runs with two AA batteries.
