Students from 10 secondary schools took part in a 'Thinking Black Box Exercise' which aimed to promote creative thinking. The project was organised by the Zuni Icosahedron arts organisation. Started in 1995 as an artist-in- residence Community Art Project, the black box exercise promoted multimedia art installation activities. According to Zuni Icosahedron, a black box provides an ideal space for the imagination, creativity, thinking, forming opinions and communicating. For the Thinking Black Box Exercise, 10 secondary schools produced 20 mini black box installations for an exhibition. All the installations were based on a given theme: invention. Joanne Chan Yee-chong, 15, and Linda Leung Wai-wah, 15, worked together to create a black box. The two Form Four students from Rosaryhill School put a plastic ball in the box to combine the sphere with the black square cube. 'I feel there is something mysterious and novel about the black box. If we are creative enough we can get anything out of the black box,' said Wai-wah about their product. Yee-chong thought that the project was a good opportunity for students to be creative and imaginative. She admitted the heavy study load for the school curriculum prevented students from spending more time on such projects. Therefore, she hoped their school would organise more activities to stimulate creativity. Another participant Cheng Yin-ying, 16, related the idea of invention to environmental protection. The fourth former from SKH Tsoi Kung Po Secondary School said that new technology sometimes destroys nature. 'New inventions improve the quality of our lives, but at the same time they may harm na ture. I hope human beings will think more about nature when they work on new technology,' Yin-ying said. Pointing at the silver roses in her box, she said technology may destroy all living things and everything would become artificial very soon. She was also happy and excited about having others admire her creation. 'The box is limited in its size and shape, but for creative people, space for the imagination inside the box is infinite,' she said.
