As Donald Trump completes his first 100 days in office, Chinese artist Ai Weiwei released a limited edition skateboard (a devilish number of 666 are for sale) which sees him flipping the bird at the White House.Study of Perspective: The White House is a collaboration with The Skateroom and a continuation of his wider series shot between 1995 and 2003 where Weiwei sticks his finger up at different buildings around the world which are symbols of authority. It's being launched at Art Market in San Francisco, along with another from artist Shepard Fairey, and profits will go towards art institutions and non-profits."My favourite word is 'act'," says Weiwei. "I am partnering with The Skateroom for that very reason. During the filming of Human Flow, my documentary on the global refugee condition, I had the opportunity to speak with individuals from both B'Tselem and the Bridging Peoples Association in Turkey. What these two organizations do is very valuable to society, both in fighting against injustice and in helping those that are unfortunate."theskateroom.com
