Minarets in the Netherlands, Mohammad in Denmark
I don't think it's easy to insult all of Europe with one artwork, but David Cerny certainly did a good job of it with Entropa. He convinced the Czechs he was going to create a multi-national project for them with artists from throughout Europe, but instead made a sculpture himself where he insults each and every country.
The Netherlands: flooded, with just the minarets above water
Denmark: Mohammad built with LEGO blocks
