Korean toilets

One surprising thing I came across here in South Korea were the toilets. Even your "ass" will feel like in silk!  

Not only that public toilets are VERY clean and free(still don't understand why toilets are so horrible in Prague although you pay for it in subway), but you can find them at every corner. 

That's one big plus point for Seoul, but it is not what I wanted to point out. I feel in this country as in geeks heaven, everything seems to have some electronic feature. And even on plenty toilets you can find some mysterious buttons.

 Maybe after pressing them for the first time, you'll feel raped. In fact it was my first time I used bidet so I felt that way but now I am used to and I would fancy to have such thing at home. But it's not only bidet, you can turn on ass( :D toilet seat) heating, dry wet parts of your body and probably it can even make dinner for you. At least I have no idea what is function of the 4 other buttons.

I am surprised I have never seen such thing in Europe. I reckon it could be great business idea - one could easily upgrade your existing toilet with special toilet seat cheaply manufactured in China.
