Four shades of red: To honor Karl Marx' 195th birthday, artist Ottmar Hörl set 500 of these sculptures up throughout the philosopher's hometown of Trier, a city in western Germany near the border with Luxembourg. The different shades are reportedly meant to suggest that Marxism can be interpreted in more than one way.
