The t-shirt folding thing is great.

Anyone know something similar for any other type of clothes?

You can easily fold a shirt with a sheet of paper.

Here is a video (she uses a magazine, but you just need a single sheet) : https://www.youtube.com/watch?v=2yaMc9Sz-YE

Probably not as fast but very effective if you need to travel with a couple of shirts.

A woman named Konmari is famous for doing this kind of thing for everything.

I believe the woman to whom you are referring is named "Marie Kondo".

The NYTimes wrote up a fairly lengthy article about her in July 2016, which I've been meaning to read: "Marie Kondo and the Ruthless War on Stuff". [0]
