Fast Tuned Skull - modern art in Prague

One of the Czech Republic's most well-known sculptors is a guy named David Černý. He is the man responsible for the creepy babies on the tower (which are rather fun), and various other well-known bits and pieces around Prague. This skull is one of his works that I see every Monday on my way to a lesson in Prague 7 - Holešovice. It's on the roof of a contemporary art gallery, Dox.
