This seems a nice way to protest the jailing of Chinese artist Ai Weiwei. One of Ai's works, Fairytale-1001 Chairs, involved just that: 1001 Chinese chairs, assembled in a room and then distributed around the German town of Kassell.
So the plan is to recreate the work tomorrow, by bringing chairs to Chinese embassies worldwide, and staging a thematic sit-in:
This Sunday, April 17, at 1 PM local time, supporters are invited to participate in 1001 Chairs for Ai Weiwei, by bringing a chair and gathering outside Chinese embassies and consulates to sit peacefully in support of the artist’s immediate release.
Incidentally it's not just artists supporting Ai. Apparently Ai was a serious gambler, and his blackjack buddies are getting together to support him. Hence the wonderful title "Arrested Chinese Blackjack Guru Ai WeiWei also an Artist and Activist". See, people churning out dubious online articles to promote online gambling can occasionally produce works of pure, self-parodying genius.
