I like that, that is, the new take on UI with having vertical script. I mean there was a design website posted on HN the other day (it was a list of colors I believe) which also had vertical (English & Japanese) text.

The closest I've worked with is a booking website for an international parcel delivery company. We offered the application in idk, dozens? of languages. Hebrew was one of them, it's a right-to-left language and our whole website became right-to-left when switching to that, so the main menu was on the right instead of the left, things like that. Great work by our CSS people.
