The work 'Screensaver' was made in response to an incidence when PBS (a major US broadcasting service) had shown archival footage from previous years’ firework shows in a ‘live’ broadcast, as poor weather conditions had affected the quality of 2016 display. The artist collected footages of the broadcast in question, and altered them into pulsing lines and colors by zooming into the image. The soundtrack of 'Screensaver' consisted of a computer-generated ambient composition, and a recording of reactions to the visuals, performed by members of 'Hong Kong Voices' – a Hong Kong-based chamber choir. The results are combined into a working computer-screensaver.
