Over the next three months we'll be constructing huge yellow 'walls' in major cities across Australia. The walls represent the Chinese internet censorship regime known as the Great Firewall of China. We want members of the public to dismantle the walls, brick by brick, in the run-up to the Beijing Games. But we need your help!

Over the next three months we'll be constructing huge yellow 'walls' in major cities across Australia. The walls represent the Chinese internet censorship regime known as the Great Firewall of China.

We want members of the public to dismantle the walls, brick by brick, in the run-up to the Beijing Games. But we need your help!

We need volunteers to guide members of the public to the walls and explain how they can take action.

In each of the 20,000 bricks which make up the walls is an 'action card' addressed to one of the large internet companies who help the Chinese Government censor internet users in China.

Media giants like Yahoo!, Google and Microsoft, and some less well-known in the West, such as Sohu and Baidu, assist the Chinese Government to block the internet when people either search for or post information the Government deems inappropriate.

Our action cards call on these companies to stop assisting the Chinese Government to violate human rights.
