Ai Wei Wei, an artist from China, recently did a Psy "Gangnam Style" parody.

Ai tweeted this video on Wednesday of him and his colleagues dancing at his studio in Beijing. He is the current topic of career retrospective at the Hirshhorn Museum located in Washington.

He said that he is unable to attend the show because Chinese officials still have his passport. Ai Wei Wei has gained fame internationally because of his free speech activism; he was put into secret detention last year and released after 81 days.

Psy's "Gangnam Style" music video has currently surpassed 530 million views on YouTube and has ranked number 4 for 'most watched videos' of all time.

He has ranked number 1 on iTunes in 30 countries and has ranked number 2 on the Billboard main single chart Hot 100.

He has also recently signed a contract with Justin Bieber's agency and plans to release his first U.S. single sometime in November.
