Synopsis: Virtual Terrain has been in composition since 2012. It is created successively after “Flâneur in a Virtual Landscape” which is a series of digital prints. Like Flâneur, Offset is also an audio-visual work generated by digital images generating program. When I use computer as my environment for artistic creation, the software and the operating system constitute an interesting world full of symbols to me. It consists of actual and virtual realities in the meantime. Being a creator and a loner in this parallel planet, I take position as a photographer and a rover, keeping filming these virtual scenes, making and adding granularized noises to this space I created. Through the process I would like to share with the viewers feelings of illusions in the nonphysical space as well as the unspeakable phenomenon filtered out in a medium alternating.
