Hmmm. It's fun and unusual, yes, but I'm not convinced by the science of it.
Having said that, I am right handed, but both my mother and father are lefties, and I've known quite a few left-handed people over the years, and none of them have ever a) had any trouble telling the time, or b) questioned the whole 'clockwise' thing.
Still, it is something different, and I'm all for that :)
My wife is lefthanded, but she said too, doesnt looks different. But you know, the scientist are smart :D
