Four trams carrying students' artistic creations hit the road last week. ArTram In Motion is part of the Arts Ambassadors-in-School scheme, which encourages young people to develop their artistic potential. Although the scheme is now in its third year, this is the first time students' artworks are appearing on this form of public transport. The ArTram In Motion competition attracted entries from 247 primary and secondary schools. Students had to create models with the theme 'New Toys of Old' or 'Original Playground'. Pictures of winning models from 12 schools will be displayed on local trams for a month. Ko Tin-lung, chairman of the Hong Kong Arts Development Council's arts promotion committee, said trams represent the city's history and culture. 'They are closely related to the Hong Kong public. We are using trams to spread the message of the development of the arts,' he said. Ko said he hoped student artworks could be seen on other forms of transport, such as buses, next year. Three students from the Queen Elizabeth School Old Students' Association Tong Kwok Wah Secondary School won the grand prize with their model, called 'The Friends'. They made a clown with paper clay, its right hand holding a Ferris wheel and in its left hand a merry-go-round. The background is black and white - a stark contrast to the colourful clown. Student Yip So-ping, 17, said Hong Kong people led a hectic lifestyle. She said the idea behind the Ferris wheel was to try to persuade people to stop for a moment and enjoy the beauty of the city. It took three days for the team to finish the model, she said. ArTram In Motion is co-organised by the Arts Development Council and Hong Kong Tramways.
