You could probably order those hinges online and give them to your glass people for them to install (do that before the glass is tempered so the proper holes can be drilled).

I looked that the videos and wouldn't want a door that took so long to close. Or one that played music (haha). It is fine for a glass door in an office. Wouldn't you rather have a door that swings both ways on a self centering hinge?

i guess i want self-closing because I'm afraid someone will slam the door accidentally....

But yes I notice the self close only allow one way instead of full rotation.

By the way, what's self centering hinge? Saw and read that in many article, but I don't know what it means technically.

I thought one of the door examples in you links did go both ways.

My old shower door (previous home) wasn't self-closing, but you also couldn't slam it shut. Not sure what kind of hinges were used.

Shower glass door on hinges are so heavy they don't "slam". With a self-centering hinge there is nothing to "slam" into, and it can swing in or out. You can put the door pretty much in any position you wish. If you really push it hard, it will go slightly past center then come back, self-centering, in the closed position. If you can find a local glass/mirror/shower door company, they usually have ones set up for you to try.
