Lech Walesa, former Polish president and founder of the Solidarity trade union, gestures as he speaks during a multimedia performance directed by Robert Wilson titled "Solidarity. Freedom is the Name of Your Angel!" at Gdansk Shipyard, Poland, Tuesday, Aug. 31, 2010. The event celebrates the signing of the Gdansk Agreement on Aug. 31 1980, an accord reached after a series of labor strikes by shipyard workers in Poland which gave the Solidarity trade union the unprecedented right in communist Europe to strike and organize itself as an independent union.
