Sometimes, it's the odd ideas that spread
Apparently, the folks who run one of the big airports in Europe became famous because of a clever idea they installed in the airport men's room (click on picture for details... this is a family friendly blog).
Apparently, the tiny silk screened image dramatically increases the quality of aim and thus the cleanliness of the bathroom.
What amazed me is that I saw this very same urinal in three or four different restaurants and public places over just three days in Amsterdam.
What is it that makes this sort of innovation feel safe?
