What caught my eye last week was an art installation by the Chinese artist and dissident Ai Weiwei. He put surveillance cameras up in his house in Beijing, four of them in all, and earlier this week he began streaming them live on a website call Weiweicam.
This was a protest against another form of surveillance, this one by the Chinese government - the police cameras trained on his house, the frequent searches Ai says he is forced to endure and the monitoring of his phone and computer.
But in a move that may not surprise you, four days later the Chinese government told Ai Weiwei to take down the website.
