Self explanatory really.
Ai Weiwei is still in the custody of Chinese officials. No one has heard from him since his arrest on April 3rd 2011.

Chinese artist Ai Weiwei was arrested by government authorities last Sunday.
No-one has heard from him since.
A foreign ministry spokesman claims Ai has committed economic crimes and that the arrest is legitimate under Chinese law.
How legitimate and lawful is the utter silencing of one of your citizens?

Taken from David Aaronovitch's comment in today's Times. No link though because of the paywall.
In summary of (and in agreement with): If the Chinese government feel the need to crackdown on those who support a different political agenda; how can it claim to truly speak for its people?
Topicality Is All In Journalism is the distillation of current affairs, news articles and items of cultural note into poster designs and written commentary. It has been devised to promote the level-headed and rational sentiments made by others in reaction to current happenings – be them local, national, international or universal.
The aim is to have a constant stream of visual output that draws from the range of topics being discussed in the public realm. The posters are designed to play with the conventions of advertisements and other public visual material as a means of presenting unexpected motifs within a mostly commercialised realm of printed communication output.
Visitors are actively encouraged to participate by promoting the opinions they feel an affinity with by printing copies of the posters to display in their area.
The Topicality posters will soon be available to order as digital prints and to download as high resolution digital files in a not-for-profit capacity.
This project is run in-conjunction with the National Diplomatic Rhetoric’s ongoing poster campaign to encourage public thought and debate through material that attempts at a neutral and honest communication of facts and ideas.
