Greenpeace invited LEDARTIST to be the artistic partner in establishing an iconic Countdown Clock, counting down the days to the opening of the UN Climate Change Conference in Copenhagen in December 2009. As well as the countdown clock itself, the MIST display will also show a slide show of global climate change effects, particularly the Arctic. The launch ceremony for the installation took place at East Point City in Tseung Kwan O, Hong Kong on 28th May, and then be exhibited in New Yuen Long Centre and Tsuen Wan Grand City Plaza till December 2009.
