This series video were developed during a residency at Rijksakademie, Amsterdam in 2006 and premiered in the Open Ateliers 06. It is parts of an ongoing action project, conveying varies video documentations of my actions taken place in Taipei, London, Liverpool and Amsterdam from 2002 to 2006. Here I tried to expose an invisible reality that governs our ordinary life. Projecting the time track of the past on the reality of Amsterdam is the fantasy of ‘Invisible City’. So to speak, the work attempts to pin down the vacuumed hyper urban vibe to be parallel again with the real watermark on earth.
