It's been claimed that hackers have tapped into the official website of the Beijing Olympic Games to colour some of its headlines orange in support of a protest against human rights abuse in China.
Danish human rights activist and artist Jens Galschiot is pushing people to get involved in The Color Orange project ahead of and during the Olympic Games, which start tomorrow.
He wants athletes, politicians, journalists and others in Beijing to display something orange, and is urging people around the world to hang up orange cloth strips on sculptures, lampposts, fences and other visible places in cities as a way of criticising China over its human rights abuses.
Mr Galschiot said he received an anonymous phone call claiming that hackers had changed the headlines of the official Chinese Olympic website into orange, seemingly in support of the project.
"I was rather sceptical about the message but I've checked the website ... actually the headlines are orange," he said in a statement on his website thecolororange.net.
"But I dare not say whether hackers or a humanitarian-minded web designer are the originators.
"These hackers must be exceptionally skillful if they have managed to make this small but very powerful change of the official Olympic Games websites."
But, Mr Galschiot added, he did not defend unlawful hacking of websites.
The en.beijing2008.cn site had its main headlines in blue this morning, but smaller headings were all in orange, as were some other elements of the design.
Australian Olympic officials were not available for comment this morning.
