Well, actually this is quite old, but it hasn’t come to my attention till I saw it on a German talk show on Friday. Looks like there’s a rather quick method for folding t-shirts that originated in Japan. Here’s the full description of it – including a video - and what advantages and disadvantages it has.

Since I always mess up when folding t-shirts this trick is really an improvement for me. I haven’t tried it with long sleeve shirts though with a small modification it is said to work with them too.
