The whirring in the air looks unreal, more like a video error than a real object. The artist Ai Weiwei remade his installation „Forever Bicycle“ for an exhibition in Lisbon. Originally created in 2011 for an event in Taipei, it has been seen – in ever-changing variations – in several cities. Now it is the eye-catcher in front of the exhibition venue Cordoaria Nacional where the largest Ai exhibition to date is taking place until Nov. 28. Thereby, the artist is also thanking his new home country Portugal. He moved to the small town of Montemor-o-Novo in spring after being fed up first with Berlin and then with Cambridge. The town is best known for its production of corks. How long will the restless spirit stay this time?
