The stated reason for visiting Brussels this weekend was to see the controversial Entropa exhibit -- originally claimed to be a composite of 27 different artists' works, each of their own EU nation. Instead, it was all done by David Černý. It's controversial because none of the pieces are flattering, though almost all are hilarious. Unfortunately, the Bulgarians didn't think that being represented as a ceramic pit toilet was very artistic, so now they're just a black sheet.
For the descriptions of each piece and a link to the PDF containing full descriptions by the original "artists", go to the Wiki page.
