How to Fold a Shirt

So I thought this interesting science article was hard to understand until I saw this amazing thing. I of course have some sort of brain deficiency when it comes to folding, and simply do not get this. Swear to God, I've watched the darn thing about twenty times, and I still can't do it. I think it is a sign that Hiroshi should do laundry forever. He can fold shirts like this.
