This _has_ to be a multinational government program. :-D
You've got to admire restroom floors with "No Step" warnings on them:

That sort of defeats the concept of a "floor" doesn't it?
Also, if you aren't supposed to step on it, why is the floor's surface
textured to assure good traction?
In fact, why do you need good traction in zero g? You try to walk on the
floor you aren't supposed to be stepping on, and you'll just float right
off of it anyway.
Also, check out the adjustable height foot restraints on the toilet...
in the full-up position, this toilet is perfectly set up for Yoda to
use. :-D
That's from here, BTW:
