Prisoner of the exhibitions of the artist Ai Weiwei United Kingdom

The Chinese artist Ai Weiwei has disappeared. But look around, and it seems to be everywhere.

More than a month after one of the most famous contemporary artist from China was arrested trying to board a flight to Hong Kong, in his name, his face and his art was arose around the world.

His colleagues in the international art world say they want to ensure that it disappears from the point of view.

"Liberation Ai Weiwei," reads a message inscribed on top of Tate Modern Britain, one of the attractions of most visited in the country. This week, two major exhibitions of artist's work are dating in London - including in Somerset House in the capital, a place of prestige which hosts the biennial capital fashion week.

In Paris on Monday, British sculptor Anish Kapoor, probably best known to Americans for his reflective, pivot of bean-like frozen at Millennium Park in Chicago, has dedicated his latest monumental work, entitled "Leviathan," the Chinese artist - even though he acknowledged he had never met.

"He is a colleague, an artist," Kapoor told the Guardian newspaper. "In a very simple way, he is heroically saving human existence."

In New York, Mayor Michael Bloomberg joined artistic city community in honouring the IA to Pulitzer fountain Manhattan last week, telling the assembled audience fearlessness of the artist at official intimidation spoke of "the indomitable desire for freedom that is within every human being."

In China, which is thought to be held secretly by the State security, activists artists also made their voices in support. Hong Kong, which has its own separate legal system, its similarity templates have been sprayed around and even laser-projected onto the local army garrison building.

Despite the growing outcry, China refused to answer the question on the fate of the artist.

"This case remains under investigation and those outside people should refrain from comment", Ministry of Foreign Affairs spokesman Jiang Yu said Tuesday.
