>In Norway, government-funded construction projects exceeding a certain cost must include artwork. I'm a swede and I am constantly pleasantly surprised by public policy in our scandinavian countries.
It's not only in Scandinavian countries. Many countries, such as Germany and the US adopted that policy at the end of the 1920s or beginning of 1930s. In the former it's still in place and Wikipedia tells me that more than half of the US states have a "Percent for Art" program which is essentially that.
