The mass campaign here to depose President Chen Shui-bian veered hard into weird territory this week. Campaign leader Shih Ming-teh has stepped aside, and the new face of the anti-Chen campaign is a wheelchair-bound advertising executive with ideas that no screenwriter could make up. He is Jerry Fan Ke-chin, who used to work for Mr Chen when he was mayor of Taipei. Mr Fan claims authority to lead the anti-Chen movement solely because of his self-proclaimed 'creativity'. And there's no denying that he has given the demonstrations a new flair. Taiwan's opposition movement from the 1970s through to the early 1990s was dominated by a deep sense of seriousness. Recently, political demonstrations have become celebrations of Taiwanese identity - especially those organised by Mr Chen and others in the pro-independence camp. But the anti-Chen protests of recent weeks have often had an angrily resentful nature, attracting the political lunatic fringe and nationalistic elements of the underworld. Now Mr Fan wants to change all that by giving the movement a pick-me-up. He began late last week, telling all participants at a planned protest on Saturday to wear red. Next, he built a giant wall of speakers to blast classical music at the Presidential Office. On Monday, it became clear that Mr Fan's creative juices were really starting to flow. He announced a new logo for the campaign - a headless, red stick figure inspired by the mysterious Nazca lines drawn in a Peruvian desert by an ancient culture. Mr Fan expects hundreds of thousands of red-shirted marchers to form 'Taiwanese Nazca lines' on Saturday in the broad boulevards facing the Presidential Office. According to Mr Fan, the headless, stick figure is a kind of compass - to remind the scandal-embroiled Mr Chen that he is encompassed by the law. At the same time, he says, it represents a Taiwanese aboriginal warrior shaking his spear in anger at Mr Chen. Mr Fan wants Saturday's demonstrators to march clockwise, around one of Taipei's old city gates - to evoke the 'dharma power' of Buddhist monks parading around a stupa. He compares this to the siege of Jericho by the ancient Israelites. Like the biblical prophet Joshua, Mr Fan wants to march his warriors around the Presidential Office until it collapses miraculously. There has been much grumbling in the anti-Chen ranks that Mr Fan's creativity is robbing the movement of its solemn moral authority and wide support. But his real problem is that his music, logo and symbolic references have no meaningful connection to the Taiwanese identity. Further, they represent one man's rather fanciful creative imagination being imposed on the movement's supporters - rather than a grass-roots expression of the movement's political imagination.
