Mr Eugene Seow, 18, putting the finishing touches on a Lego structure representing his vision of Singapore, featuring cable cars as well as the towers of Marina Bay Sands. He was one of about 1,000 students from Republic Polytechnic who took part in a two-week competition to design and build a Lego structure with a Singapore theme, to celebrate the country's Golden Jubilee. The students, who formed 190 teams, worked to the theme, Modern Brick City - Build Without Boundaries. They used commemorative SG50 Lego brick sets provided by the Ministry of Education and from their personal collections, as well as recycled materials. Yesterday, three top teams were chosen based on their creativity, design concept and relevance to the theme. The winning team will be announced on Aug 6 and stands to win $300 in cash vouchers, with their structure displayed on the campus.
