Folding T-shirts

Here's a link to a video demonstration on how to fold a t-shirt. The commentary and captions are Japanese. I don't know who posted it on the web, or why, but it's a nifty way to fold.

I used to work at the gift shop in the Hyatt Regency Hotel on Kalakaua Avenue in Waikiki. We had a huge table of t-shirts at the front of the store, almost on the sidewalk. Every night before closing at 11 pm we would have to fold every t-shirt and sort them by size. Back then (the late '80's) most of our clientele was Japanese and most of the staff was nisei, born in the US of Japanese born parents. My coworkers were convinced that everything done the Japanese way was superior and they spent hours trying to reteach me similar things like how to wrap a gift. Still I don't remember this particular method of folding shirts, even though it is a superior method.

Could there have been, somewhere in the world, a quiet revolution in laundry folding techniques?
