Andy Lau Tak-wah isn't just interested in acting and singing; special effects attract his attention too. Attending the Macro Interactive Media Arts Exhibition, A-Glow Glow, last Friday, Lau (right) tested firsthand two multimedia artworks installed along the Avenue of Stars. One is called Phaeodaria, by local artist Teddy Lo Yeung-man, which creates sounds on Bluetooth sensors within its vicinity. Even more intriguing for Lau was the other piece by London art group United Visual Artists (UVA). Using 46 LED panels, Volume conjures both waves of sound and colours when you pass through its surroundings. Doing a little dance among its sensory poles, Lau immediately thought about future applications for his concerts. 'I have always been interested in putting different visual and lighting effects to my concerts,' Lau said. 'I want to prove that Hong Kong singers do not just sing standing still on stage. There are all sorts of things that are possible.' The entertainer even met the two designers, Lo and UVA's Chris Bird, backstage. Maybe Lau's curiosity had to do with UVA previously working on shows for U2 and Kylie Minogue. 'I spoke to him about how all these can be applied to my concerts ... it would be fun but, unfortunately, he told me it would take at least two to three full days to set up the device. Honestly, we don't have that much time for shows at the Coliseum.' To see more of the installations, visit scmp.com/multimedia. The works are there until April 20.
