While this thing is bumped to the top I may as well mention that after seeing the toilet video, I actually went out and bought myself a Japanese toilet seat, or "washlet." It just so happened that my brother (who is also my flatmate) had used one recently at one of his Japanese friend's parents' house and was very impressed, so we both went in on one. We got a Toto S300, which would only be a mid-level model in Japan but is the highest-end washlet you can get in the States without replacing the entire toilet. It has two ass wash modes (regular and soft) plus the vagina wash, all of which can be further adjusted by another 5-position pressure control. Also has 5 water temperature settings, 5 heated seat settings, a deodorizer fan that turns on when you sit down, oscillate and pulse modes, self-cleaning features, an air dryer, and of course the hydraulic soft-closing lid. It's also controlled by a wall-mountable wireless remote. I got a pretty nice deal on it of course.
I can't live without it now. On the rare occasion that I'm forced to take a shit at work or at a friend's house I just feel tainted afterward. You don't realize how dirty a paper-only ass cleaning leaves you until you've seen the light with your own eye, so to speak.
