A weird innovation: for people like me who always wondered why there is a fly in European urinals, here is the answer, thanks to Seth Goldin:

pparently, 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.

Great innovation to increase the urinal shooting abilities, did some people ran ethnographical studies to come up with this?!!!
