The demolished Star Ferry clock tower in Central lives on in Victoria Park - in the form of tens of thousands of inflatable replicas on sale at the Lunar New Year fair. Architecture students have recreated the tower in the form of an air-filled 'tumbler' toy to keep memories of it alive. And unlike the real one - now just part of the city's so-called collective memory - the replica is weighted at the bottom so it can never be knocked down. 'No matter how hard you hit our inflated clock tower, it quickly rights itself and stands up,' Zhuhai College architecture student Ngai Fung, one of the designers, said. 'What we want to say is, 'the clock tower never falls - Hong Kong never falls!'. We developed the idea around September and October when society was having a heated debate about the fate of the tower. It took about five months to turn our design into a real product.' Collective memory of the tower may be priceless, but customers can take home a replica for HK$68. City University architecture student Lai Fai said they hoped their creation would raise people's concern about heritage conservation. 'Most of us are architecture students and felt upset when the government insisted on demolishing the tower. We have the responsibility to tell the public we should cherish our culture heritage,' he said. And lest anyone forget the man ultimately responsible for heritage conservation, replicas of Chief Executive Donald Tsang Yam-kuen are on sale. Elsewhere it's pigs galore, as befits the start of the Year of the Pig, but even among these, the bow tie-wearing chief executive isn't forgotten. About 20 Form Six students of Hong Kong Wah Yan College dressed up in white T-shirts with bow ties painted on the front to sell their range, including pig cushions, environmentally friendly shopping bags bearing a pig logo, and toilet roll covers in the shape of a pig's head with the paper coming out of the nostrils. 'Most tissue covers only can contain one roll of toilet paper, but two rolls can be fitted inside our tissue covers,' product designer and Form Six student Alex Lau Yin-tung said proudly. While dry goods stall operators have only just began doing business at the park, flower farmer Lau Hoi-tao said all his peach blossoms were sold yesterday. 'The biggest one sold for about HK$60,000, about the same price as last year,' he said. The fair, which began yesterday, will last until February 18. Police reminded drivers that roads around the park, such as Cannon Street, Paterson Street, Great George Street, Sugar Street and Kingston Street, might be closed depending on the crowd and traffic situation between now and Sunday.
