War, French Style

From Yahoo:

We all work hard at the office, right? Of course. But sometimes, you have to take a break and let off some steam. And sometimes, a challenge must be met, and a battle joined. Thus it was that when employees at Ubisoft Montreuil in France decided to blow off some creative steam by decorating their building's windows with animated characters created out of Post-it notes, their neighbors across the street at BNP Bank declared a Post-it War.

How stereotypical.  The French would rather make art than work.  When I first saw this, the first thought I had was "what about all of the lost productivity?"
