Michael Jackson's famous moonwalk has returned to the stage in the form of a shadow puppet designed by Hills Lee, a third-year student at Baptist University's Academy of Visual Arts. Along with 11 other students, Lee is learning traditional puppet-making skills from Wong Fai, of the Hong Kong Puppet and Shadow Art Centre. Leung Mee-ping, an assistant professor who introduced the course to the academy, said it aimed to inspire students by showcasing the innovation of ancient craftsmen, and to preserve the valuable tradition of shadow-puppet art - one of the earliest forms of animation. 'I admire the way craftsmen invent and make their own tools. This is rare nowadays, as people can just buy ready-made materials or tools from shops,' Leung said. The two-dimensional puppets, traditionally made of leather, are controlled from behind a screen. Dating to the Han dynasty (206BC to 220AD), they were used to tell stories about wars, legends and myths. Students made their puppets from plastic film or card, transforming an ancient art form by using modern materials. One of the challenges when making puppets is to ensure that they move vividly, with the joints moving smoothly. Wong said this could not be planned but had to be imagined and tested. Puppets of human figures have about 11 joints, with finer movements, such as those of lips and fingers, controlled using mechanisms consisting of rods and elastic bands. To capture the essence of the way Jackson danced, Lee watched several DVDs of his concerts. His puppet has not only a movable part at its waist emulating the tail of Jackson's tuxedo, but also separate toecaps that allow it to perform the famous moonwalk. Leung said the art form remained largely unexplored by contemporary artists and she hoped one day to set up a street shadow theatre in Mong Kok where students could perform.
