Andy. This one is for you. This is a typical toilet for a nice restaurant here in Japan. The dials and stuff on the left side are for the heated seat, the bidet feature, the synthesized flush sound, the bird's chirping sound, and the air freshener. The little black rectangle at the back of the seat is the infra red or motion detector to detect your butt - wouldn't want to turn on the bidet without a butt on the seat. Oh, the comfort!
